Welding Common Joints Using Flux Core Wire MIG Welder

Welding Common Joints Using Flux Core Wire MIG Welder

 Welding Common Joints Using Flux Core Wire MIG Welder

Introduction: 


Flux core wire welder, introduced in 1935, follows the similar technique of a MIG welder. Both use similar equipment and continuous wire feeding. Both get the power supply from the same machine. They run semi-automatically and have a very high production rate of common welding joints. The key difference lies between them is in terms of shielding the electrode from the air. Unlike MIG welding, it gets shielding from the flux core that exists within the hollow wire electrode that helps you not to carry a gas tank for the welding. One of the major advantages of the flux core welding is you can use it for outdoor purposes even in any windy environment. You can say, this is a MIG welder with an attribute of SMAW welder. 


How Fast is This?


The Flux core wire MIG welder is the most productive of all available manual welding processes. It can weld common joints for more than 25 pounds per hour. Furthermore, it can weld ½ inch plates in a single pass on both sides with full level of penetration. That is why Flux core welder is the first choice for use in the shipbuilding industry. Even in windy situation it provides a fast, reliable, and quality weld. 


Guide to Flux Core Wire MIG Welding:


Safety Preparation:


Before starting any welding project, you need to ensure you possess the required safety apparels ad you have removed the probable fire hazards from the project area. You need to have leather boots or shoes, long-sleeve & flame resistant jacket, full-length pants without cuff, leather gloves. Safety glasses, bandana or skull cap, and welding helmet that will protect you from spatter and sparks. 


Metal Preparation:


Although flux core welding is highly tolerant of surface contamination, you should clean the surface thoroughly beforehand so that no rust or scale can contaminate the final weld. You can use either a metal brush or a grinder for cleaning. Apart from cleaning the surface of the metal, you need to clean the portion of the metal where ground clamp gets attached. For complete fusion of both parts of materials over ¼ inch, you should always bevel the edges.


Equipment Preparation:


Before you strike the arc, check all the equipment properly that there are tight connections of all cables, and they are free of any damage or wear & tear. The Flux core wire MIG welding requires either a straight polarity or a negative DC electrode. So you need to select the polarity of the electrode perfectly. You have to use the right drive rolls as the flux core wire is softer than the solid one. Right drive rolls don’t let the wire to become compressed or deformed. You should check and adjust the wire tension by following the owner’s manual. You may experience a poor wire feeding performance if the wire tension on the drive pools or the sire spool hub is too high or too little. Furthermore, you need to check the consumables so that there is no excess spatter on the contact tips, no wearing on the contact tips & liners, and rust on the wire.


Selection of Wire:


If you apply the flux core wire MIG weld on mild steel, then you can conveniently use the E71T-11 designated wire for any position. It is available in different sizes and suitable for outstanding welding features for both thin and thick metal. The wire diameter of 0.30 inches is good for applying for a variety of metal thicknesses. If you need to weld a thick metal at a high level of heat, it is better to use wire with diameter ranging from 0.35-0.45 inch. 


Voltage and Ampere: 


Depending on the factors like metal thickness, welding position, wire diameter, and joint configuration, you can determine the voltage and amperage requirement of a weld. The power source has a reference chart that dictates the necessary level of voltage. It also sets the speed of the wire feed based on metal thickness and wire diameter. Welding calculator available with this welder is a great help for fine-tuning the final parameters based on some few taste welds. 


Wire Stick-out:


It is the length of the un-melted electrode from the contact tube tip, excluding arc length. Experts recommend a stick-out of ¾ inch for the flux core welding.


Push or Pull Technique:


Experts suggest that you always use a pull technique for the flux core welding. In this technique, you can tip the gunpoint at the weld pool and pull away on time. According to a rule of thumb, you pull when there is slag. 


Travel Angle:


The travel angle denotes the relative angle at which you should hold the welding gun in a perpendicular position within the level of the weld joint. 5-15 degrees is perfect for normal welding at all positions. If the travel angle is beyond 20-25 degrees, you will experience less penetration, more spatter, and general arc instability.


Work Angle:


Work angle is the position at which you hold the gun relative to the level of the welding joint. Depending on the joint configuration and position work angle will vary. At flat position, for butt weld (a 180 degree joint) 90 degree is a perfect work angle; for fillet weld (a 90 degree joint) 45 degree of work angle is suitable; and for a fillet weld (a lap joint) 60-70 degree of work angle of the gun is great for the outcome. For horizontal position, your work angle of the gun should be between 0 and 15 degrees. Vertical welding both up and down is quite difficult. You need to more cautiously pre-setting up of welding for getting the desired outcome. In vertical position, you have to face the challenge of gravity for which you will need to reduce the voltage & ampere by 10-15%. Overhead weld position is the most difficult part of the job, and you should avoid it if possible. Otherwise, use the smallest wire and lower the welding parameters by 15-20%.


Conclusion:


For the desired outcome on common joints weld from the flux core wire MIG welding, you have to practice more and more since this method requires you memorizing the correct parameters and gun travel guidelines.


MIG Welding on Aluminum

MIG Welding on Aluminum

 MIG Welding on Aluminum

Introduction:


In Metal Inert Gas (MIG) welding, a welding gun continuously feed the consumable wire electrode and shielding gas. But unlike steel, aluminum requires some specific changes that hamper the continuity. Since aluminum is softer metal, it requires a larger wire electrode to feed. Furthermore, due to high heat conductivity, you need to be aware of control of power supply and the filler feed rate. Our guide will give you a detailed picture of how to MIG weld aluminum successfully. 


How to Aluminum Welding:


Aluminum as a soft metal requires alloys to add on for getting strength. It has a greatly varied property that those of steel. So welding on aluminum has some unique challenges. You should be more cautious while welding on aluminum since it is prone to distortion and sensitive to heat. Nevertheless, if you follow our guidelines and use the right equipment, it is not very difficult to successfully MIG welding aluminum. We present some important factors that you should bear in mind when you apply MIG welding aluminum.


1. Consider Material Thickness: 


The thickness of the aluminum you are going to MIG weld on should be 14 gauge or 0.74 inches and heavier. If the aluminum is thinner than the prescribed one, you should apply specialized pulsed MIG or AC TIG equipment.


2. Keep it Clean: 


Before welding the aluminum, we must clean it thoroughly and remove the lubricants and greases also with a stainless wire brush. You may brush manually or using power tool. But you need to be aware while using a power wire brush. Because if the RPMs and pressure are not low, attract oxides and other contaminants on the material surface. Experts recommend always using a wire brush for aluminum metal. 


3. Choose the Right Gas: 


You know that aluminum is a non-ferrous metal that requires 100% argon gas for shielding. According to the experts, you should keep the argon gas flow rate at 20-30 cubic feet per hour.


4. Use the Right Process: 


At the time of MIG welding aluminum, you should apply the spray transfer process. It ensures a smooth transfer of the melted material droplets to the melted weld pool from the end of the filler electrode. Spray transfer has no short-circuiting, and you will find the efficiency and deposition rate very high. But spray transfer is not suitable for material thinner than 14 gauge since it carries higher heat that creates large pool, which is difficult to control. 

5. Gun and Wire Feeding Options: 


You should choose the right gun and wire feeding system for the MIG welding aluminum. You can use a spool gun for feeding aluminum wire, or you can apply push-pull system. The pistol-grip style gun ensures an improved feeding of soft wires. Since the gun feeds the wire for only few inches, it removes the chance of bird-nesting. On the other hand, push-pull system is very much user-friendly and uses a motor in the gun for pulling the wire through the liner. 


6. The Right Filler Metal: 


You need to understand the alloy of the aluminum and what factors can affect the finished product if you do MIG weld on it. Highly available aluminum filler wires are ER4043 and ER5356. You can also consult with the welding distributors and the filler metal representative for the right filler alloys suitable to your requirement. 


Techniques for MIG Welding Aluminum:


Factors that greatly affect the weld-ability of aluminum are welding power supply, joint types, fit up & positions, and skill level of the operator. You can enhance your skill level for MIG welding aluminum if you following the technique as mentioned below:


1. Use push travel with a 10-15 degree angle where tip and nozzle should be in line with the travel. If you pulling or drag angle, it will lead to dirty and porous weld due to the lack of gas coverage. 

2. Keep a proper distance between tip and work and make the contact tip lower by 1/8 inch inside the nozzle.

3. At the time of MIG welding aluminum, reflective heat and weld puddle become very hot. The wire could burn back to the contact tip if you hold the tip much closer, and it would lead to other feeding defects.

4. Always avoid using large beads. Rather use multiple pass straight beads for better appearance and reducing the possibility of burn-through, cold lapping, and other weld problems.

5. If the base metal gets heated at the time of MIG welding, you should increase the speed of the torch travel.



Common Problems and their Troubleshooting:

 

Problems

Solution

Burn-through caused by overheating

·         Make the welds shorter and increase the speed of torch travel.

·         Move around on the part for spreading out the heat.

·         Use thick material and change the design of the joint.

·         Use a wire brush made of stainless steel to clean the base metal.

·         Always use proper shielding gas and wire alloy.

Wrong settings of the machine

·         Fine-tune the application or check the inside cover of the Miltermatic welder for the optimal setting.

·         Arrange a Miltermatic MIG Calculator.

Wire burns back to contact tip

·         Keep a proper distance between tip and work.

·         Make sure that drive rolls, gun liner, and contact tip size match with the diameter of the wire.

Wire Bird-nest

·         Adjust and check the tension of the drive roll.

·         Replace the contact tip when required.

·         Always check the pressure adjustment on the spool gun.



Conclusion:

Although welding on aluminum is quite difficult because of its unique properties, you can MIG weld it successfully if you follow our recommended tips and tricks. 

TIG, MIG and Arc Welding

TIG, MIG and Arc Welding

 TIG, MIG and Arc Welding

Introduction:


For the welding work, you may have a question in mind regarding what method to start. Although all the welding techniques will serve a common purpose in fabrication of metal and other plastic or melamine materials, there are some subtle differences among them. Based on your requirement, budget, and welding skill you should choose a specific model. In this chapter, we shall focus on different aspects of TIG, MIG, and Arc Welding techniques so that you as a beginner can choose your right option.


Comparing Welding Techniques: TIG, MIG, and Arc


TIG Welding:


A. How does it Work?


Gas Tungsten Arc Welding (GTAW), another name TIG, is a welding technique where you can use a tungsten electrode for heating the material and melting it down to create the welding mold. Since there is no filler material used for this method, the weld is the outcome of a single metal. However, this method allows you to use another rod as filler material for use at once to different metals or more materials. In this method, a gas bubble protects the weld from contaminations. TIG uses argon or helium as gas. You don’t need to replace the electrode since it doesn’t require feeding. You only need to refill the gas tank.


B. Use of TIG Welding:


 Welding is applicable for many materials, including steel and aluminum, quite easily. But the welding type is limited due to the thickness range. Although you can weld many materials with this method, the materials you want to weld will be thinner. Tungsten rod is thinner than a stick rod. So this method will provide you more precise scope with a thinner weld.


C. Advantages and Disadvantages:

Pros
1. It is the most aesthetically pleasing type of welding.
2. IF you want to make a sculpture or weld-on cars & motorbikes, this welding type is perfect for its thin rod and outstanding precision.
3. It is the cleanest welding type that produces no spatter and waste. 

Cons
1. It is not a favorite type for experienced welders.
2. Since it takes a much longer time to master, it has a steeper learning curve.
3. This method doesn’t suit better to the beginners.

MIG Welding:

A. How does it Work?

Gas Metal Arc Welding (GMAW) or MIG is the method of welding that allows you to feed a line of electrode continuously through a special ‘gun.’ Electrode forms an arc with the metal, fuse the material, and finally melts it down. This method uses a protective gas bubble to keep the weld away from the ambient air and other components within it. In MIG technique the wire rod as a filler material doesn’t get fused that gives you ample scope to weld different types of metals together. Since it uses consumable electrode, you need to change it frequently. Also you need to change very occasionally the gas that creates the protective bubble. 

B. Use of MIG Welding:

You can apply the MIG welding technique in various situations and for both thin & thick metal sheets. For the wide power output range and gauge of the method, you can adjust the power that allows you to weld on the softer material without the fear of burning. MIG is very powerful to weld thick steel pipes, and it provides a strong joint. 

C. Advantages and Disadvantages:

Pros
1. MIG welding is very straightforward and simple for a newbie. You need only one for its operation at any time.
2. What you need for the welding, the gun provides all the materials.
3. Controlling the gun is very easy. You press the trigger, and it stops automatically.
4. You can apply it for making an aesthetically pleasing weld and a viable sculpture. 

Cons
1. It is workable with limited materials.
2. It doesn’t suit too thin or thick materials.
3. It is very weak for cast iron.
4. It is too powerful for a thin aluminum that yields an unwanted outcome.
5. It requires clean materials. 
6. It is not applicable for wet or windy conditions.
 
Arc Welding:

A. How does it Work?

It is a flux-coated welding technique. This method, like the MIG, uses a consumable wire-like electrode and feed it continuously to the weld. The wire is flux-coated that instantly generates gas shield around the weld pool. The best part of this technique is that it allows you to use an external gas source so that you can form a second shield for providing more secured weld. So many say it dual-shielded welding. Since it uses a consumable filler material, you need to change it time and again. However, if you don’t want to use a dual-shielded arc welding, you need not change the gas tank. 


B. Use of MIG Welding:

The flux-coated welding model allows you to apply them for the heavier and thicker materials. It creates a high level of heat. So you should apply it for the metals that can withstand the high heat. Arc welding is suitable for heavy steel construction and erection, heavy machinery, heavy repairs, and such other equipment. 

C. Advantages and Disadvantages:
Pros
1. It highly efficient technique.
2. You will experience little through this welding system.
3. It provides both the shield and welding material.

Cons
1. It is not applicable for thinner materials.
2. It leaves slags that require removing and finishing.

Conclusion:

Finding the absolute best product will depend on many factors including your requirement and budget. However, if you look for a welding model that provides the strongest weld, MIG is best for varying thickness, and TIG is best for high-quality welds. If you are a beginner, MIG stands alone as the fastest welding process that you can master quickly. MIG and TIG are the best welding type for aluminum. For use on steel material, MIG is the best candidate although other types you can use as well. 

SMAW and GMAW

SMAW and GMAW

 SMAW and GMAW

Introduction:


Welding is one of the most reliable and fastest joining techniques to join and assemble metals, plastics, and ceramics permanently without the application of heat, filler, and pressure. Although there is large number of welding processes available, you can classify it into two major parts; one is fusion welding, and the other is solid-state welding. In the case of fusion welding, you can apply heat from external sources like electric arc, gas flame, resistance heating, and high-energy beam, etc. to melt down the surface of your metal to form the joining. In arc welding, arc constituted between the electrode and the base metal is the source of heat that melts down the surface metal and the filler material. Among many arc welding methods, Shielded Metal Arc Welding (SMAW) and Gas Metal Arc Welding (GMAW) are the most prominent. Although SMAW and GMAW run on the same basic principle, they have substantial differences in terms of procedure, benefits, limitations, and areas of application.


Differences Between SMAW and GMAW:


i) Continuous Nature of Electrode/Filler:

 

An electrode or other filler materials meltdown continuously and accumulates on the weld bead. Longer the length of the filler, shorter the weld time, and vice versa. For a shorter length, you need to replace the electrode frequently that would reduce the rate of production and disturbs the process. Longer filler is congenial for a longer duration, and thus it is productive. SMAW method requires frequent changing of the filler since it uses small rod and thus interrupts the process. On the other hand, GMAW method allows welding for a continuously longer time without any stoppage for changing of electrode.


ii) Preferable Welding Mode: 


You can perform arc welding in three different ways. When you perform welding with the application of filler, it is homogenous mode. If the applied filler and the metallic composition are same, it is homogenous mode. When the filler material and the metal components are different, it is heterogeneous mode. SMAW is suitable for homogeneous welding since it inherently supplies filler. On the other hand, GMAW is suitable for both homogeneous and heterogeneous welding.


iii) Electrode Material: 


Filler material like electrode should have some basic features such as electrical conductivity, desire melting point, electron emissivity, etc. Keep in mind that if there is a difference in the compatibility between the filler and the parent metal, you will face the problem of right mixing that will lead to defective output. SMAW is suitable for compatibility with ferrous components for homogeneous joining. In GMAW, most electrodes are ferrous. But you can harness the varied metallurgical composition from it for the desired outcome. 


iv) Coated or Bare Electrode: 


You will find a coated electrode for protection of the weld mode against the oxidation and other environmental contamination. Apart from protecting against the oxidation, coating has some other functions like supplying shielding gas, inducing chemical elements into weld bead, stabilizing arc, reducing spatter, etc. However, coated electrodes will cost you quietly, and they get damaged over time.  SMAW uses flux-coated electrode that supplies shielding gas to protect the consumable filler. GMAW uses a thin coating of stable material on the electrode to protect the filler material from oxidation. 



v) Shielding Gas Supply: 


At the time of arc welding, dispensing oxygen from the welding zone is very crucial, and shielding gas helps you out of this criticality. Shielding gas creates an envelope around the bead to protect it from getting oxidized. Shielding gas can come out directly from the gas cylinder or indirectly from the disintegration of chemical components at the time of welding. In SMAW method, flux coating disintegrates chemical elements to supply shielding gas. GMAW supplies shielding gas from the gas cylinder.


vi) Spatter Problem: 


During welding, you have experienced spatter that is nothing but small droplets of melted filler material. Spatter happens for the scattering of the arc. Higher spatter can lead to loss filler metal that can cause a defective & negative reinforcement with inaccurate dimensions. It is bad for appearance and may require you to grind for removing them. SMAW method produces extreme level of spatter even if you set the process parameters at the optimum level. On the other hand, GMAW method, although produces spatter, can reduce it by optimally setting the parameters.


vii) Manual and Automation: 


You can operate SMAW welding manually only. On the other hand, GMAW allows you to operate the welding in automated mode. While an automated process is fast and productive, the manual process is flexible, and you can apply it at any location. 


viii) Productivity and Quality Issues: 


SMAW is a better choice for household and general industrial purpose. You may not get a quality joint from SMAW method. In this method, you need to change the electrode very frequently that interrupts the process and thus doesn’t serve your longer welding requirement. GMAW method is highly productive since you carry out the welding for longer duration. It provides a higher volume of deposition rate and is suitable for wide root gaps.





Tips on Vertical GMAW:


Vertical Down GMAW Technique:


It is quite easy to start on the top and then work your way down. You need to tilt up the gun between the range of 35 and 45 degrees. Stay ahead of the puddle and place the filler material from the side. In contrast, the weld will not enter adequately. Till you are ahead of the puddle, patterns don’t count.


Vertical Up GMAW Technique:


GMAW welding for the vertical up position is the most challenging and difficult job. Like the vertical down technique, this position also requires you to tilt the gun from 35 to 45 degrees. For working upward on, you need to create a welded shelf. It is typically convex shaped. For the desired result, you can grind a small grove on the spot you are welding. If the metal you weld on is wide, you can expect decent looking outcome.  


Conclusion:


Both SMAW and GMAW are the arc-welding techniques that provide you handy and convenient solutions for the day-to-day requirements.


How to Weld Using TIG Welding Process (Complete Guide)

How to Weld Using TIG Welding Process (Complete Guide)

 How to Weld Using TIG Welding Process (Complete Guide)

Introduction:


If you want high-quality welding for the sectors like pipelines, pressure vessels, aviation, and food industry containers, then Tungsten Inert Gas (TIG) or Gas Tungsten Arc Welding (GTAW) is the right solution. This arc welding process uses a tungsten electrode for producing the weld. It uses argon as shielding gas for protecting the welding area from various types of contaminations. TIG method requires you to use both hands, one for holding the torch producing the arc and the other for adding the filler metal to the weld joint. So, it may be the most difficult method to learn. But it is the most versatile for use on different metals, including stainless steel and other non-ferrous metals like aluminum, magnesium, and copper alloys. Although this process is slow, it produces the highest quality weld. 


Principle of TIG Welding Process:


In the TIG process, the electric arc generates heat by playing in between the metals and an infusible tungsten-based electrode that exists in the welding torch. An inert or reducing gas shield covers the arc area to safeguard the electrode and the weld pool. The welder applies a rod like weld filler metal manually into the weld pool. TIG welding suits best to sheet materials that have thickness of 8 to 10 mm. 


Why Use Tungsten for Welding:


Tungsten Inert Gas (TIG) welding uses Tungsten that is a very hard, a bit radioactive, and a fragile metal. Tungsten is getting used for the places that require a very high melting point or the requirements to flow the electricity at a high temperature. In TIG, manufacturers use Tungsten to make the non-consumable electrode for creating the arc. Tungsten metal allows the arc to maintain the temperature up to 11,000 degrees Fahrenheit. A very high melting point and an outstanding electrical conductivity don’t let the electrode to burn up.


How Does TIG Welding Work?


You can operate TIG welding both manually and mechanically. However, the process involves both hands for carrying the torch and the filler rod. An arc is always ready in between the edge of the electrode and the workpiece. The power source setting governs the current to flow. You will require a clamp to attach the torch with the ground cable.


TIG welding follows the process as mentioned below:






Determine an Electrode:


If you have an aluminum item to weld on, it is better to use a tungsten rod. Tungsten alloys suit greatly to the metal alloys.


Insert the Electrode into Its Collet:


In the second stage, you need to fill the rod after the back end of the electrode holder gets unscrewed. You can avoid this step if you have already used the electrode.


Manipulate the Settings:


TIG welder can run in three options, namely DCEN, DCEP, and AC. If you need to weld on an aluminum-based material, you better choose AC option; and set the ‘cleaning’ option as 7 out of 10 on the scale; and set the ‘max amps’ on around 250. 


Turn on the Gas:


Gas gives the shield in welding and protects the weld pool from contamination. For aluminum, you should use argon, and for steel, it’s better to use the mixture of argon and carbon dioxide. 


Prepare Welding Table and Metal:


If your working area is congested, it will be difficult to give precision to work. An un-extended area will lead to inconvenience, discomfort, and indifference towards the work. Furthermore, the metallic area should be large enough to flow the electricity properly. 


Start Welding:


Now you are ready for the welding work. Experts suggest that you should not touch the metal with the electrode. Rather hold the electrode at least an inch away from the metal. As soon as the metal gets heated, you should start welding immediately from the edge of the object.


Tips for TIG Welding:


If you want the desired output, you can follow the tips mentioned as under:


Never touch the metal with tungsten. If it happens, you will experience a different color and sound that indicates polluted tungsten.


When the tungsten gets hot, you should loosen the rear cap to slip it out. Use a grinder for cleaning and reshaping the end of the tungsten.





When to Use TIG Welding Method:


So far, you are aware of the uniqueness of TIG welding, and it’s objective. But before you decide to use the technique, you need to know the prerequisites of the use. Under what circumstances you can apply the TIG welding method is a point of discussion below:


If the metal you have to work on is very thin and amperage setting is excessively low;

For manufacturing the racing cars;

For beautification;

For welding non-ferrous metals like copper, magnesium, and aluminum;

For getting a high-quality weld;

For welding thicker materials that require higher energy to get heat.


Advantages and Disadvantages of TIG Welding:


Advantages

Depending on your final application, you can use this process with or without filler wire.

It creates no welding smoke or residual.

It fits almost all metals and heterogeneous basic materials.

It’s a stable process, and you can apply it to all welding positions.

It provides a high quality of welding where defects are very rare.


Disadvantages

It is costlier than other welding methods.

It takes a longer time to complete the job.

It requires slightly higher energy.

It requires a cleaner environment.


Conclusion:


It will be our great privilege if you find this article on TIG welding and its overall functionalities helpful. Last but not least, you should not work with something you are not that skillful. Know the objective of your welding machine and then start working. 


How to Prevent Weld Delayed Cracking?

How to Prevent Weld Delayed Cracking?

 How to Prevent Weld Delayed Cracking?

Introduction:


Crack free weld is something that you would expect as a welder or an owner of the welded property. But Delayed Cracking or Hydrogen Induced Cracking or Cold Cracking is a very common phenomenon as the aftermath of welding. If the steel material you are working on is very strong, if there is a high level of stress for the residual or mechanical/structural loading, and if there is a source of hydrogen for the moisture in welding filler material or environment & joint contamination, you will experience the delayed cracking. So you need to eliminate and control the factors for preventing the delayed cracking from arising. 


Reasons behind the Delayed Cracking: 


There are various theories and mechanisms available that explain the reasons for the delayed cracking or Hydrogen Induced Cracking. You will find no single accepted reason for the explanation. Rather, multiple factors play behind the scene. 


According to a mass apprehended theory, hydrogen atoms get diffused through the metal and gather at spaces in the metal’s microstructure. With the accumulation of hydrogen atoms, molecular hydrogen (H2) starts to activate and react with carbon forming methane at the points of accumulation. Over time, molecular hydrogen (H2) becomes so large that they diffuse through the metal easily. Gradually, H2 creates mounting pressure to split apart the material. Thus, cracking occurs.


Another popular theory is that hydrogen atoms get accumulated around the carbide inclusions resulting in slow plastic deformation. It creates moving defects or dislocations. If the plastic deformation can no longer take place, the material becomes stiffer and fragile. Finally, the metal loses its ductility and cracking tends to occur. 


Whatever is the theory or mechanism, it is definite that delayed cracking happens when all of the following factors act simultaneously:


Presence of Atomic Hydrogen: 


At the time of welding, it is natural that some level of hydrogen is present there. It is the result of the moisture or hydrocarbon contamination. 


Presence of a Tensile Stress: 


If there is lower stress, delayed cracking will not occur. After the weld gets cooled, thermal shrinkage occurs and causes high stress. Stress concentrators like weld defects increase the level of stress.


Susceptible Microstructure: 


In case, you weld on a high strength steel structure, the output might not reach your expectation level due to susceptible microstructure that is brittle and hard. Steels with higher strength get hardened because of the presence of high carbon and low alloy that are very chronic to delayed cracking. If you weld on “austenite” stainless steel, it will not crack over time. Because it doesn’t have susceptible microstructure.  


Low Enough Temperature: 


If the temperature is at a lower level, hydrogen diffuses quite easily and thus creates cracking. Usually, 100 degrees centigrade of temperature is an industry benchmark at which level hydrogen tends not to diffuse. However, in some cases delayed cracking may happen at a temperature slightly higher than the industry average. 


Ways to Prevent Delayed Cracking:


Pre-heating:


Since pre-heating can slow down the cooling rate, it can solidify microstructure in a better way. Through pre-heating, you can expect the desired microstructure of the metal piece that is not prone to cracking. On the other hand, rapid cooling will result in Hydrogen Induced Cracking for sensitive microstructure. 


Inter-pass Temperature:


The temperature at which subsequent weld runs get deposited is called inter-pass temperature. Your welder must define the inter-pass temperature for pre-heating the base material at this temperature before placing another weld to pass. This process controls the cooling rate and helps to avoid delayed cracking.


Post-heating:


When the welding work is over, you need to apply post-heating for the elimination of remaining hydrogen. If you provide post-weld heating, the metal will give off hydrogen that will reduce the danger of cracking. This post hating also removes harmful residual stresses to get the expected microstructure. 


Suitable Arc Process:


You should always choose the arc processes that don’t tempt hydrogen in the weld metal to avoid delayed cracking. If you have to weld the high strength low alloy steel material, experts recommend surface tension technology of MIG welding. You should not use stick welding in this case. Otherwise, cellulosic electrodes will cause to diffuse hydrogen that will lead to severe cracking in the steel material.


Suitable Filler Metal:


Filler metal like cellulosic stick electrodes may contain moisture and other organic compounds that are responsible for delayed cracking. These electrodes with moisture create gas shielding with hydrogen. So, you should always use basic electrodes that use minerals like calcium and magnesium carbonates. These basic electrodes provide low hydrogen shielding and reduce the risk of cracking.


Multi-Pass Technique:


The multi-pass technique through its tempering effect can modulate the microstructure of the steel material for reducing the hydrogen content. It starts with a deposit pass and the next pass tempers the earlier to protect it from delayed cracking. You can apply the hot pass for the same purpose. Hot pass clears the root pass and thus remove the slag content. It also provides heat treatment to the root for protecting it from getting cracked.


Temper Bead Technique:


In cases where post-weld heat treatment is challenging, temper bead method is useful for these. It helps in self-heat treatment to refine the zones of course grain. It ensures improved properties with wanted microstructure. Furthermore, it helps to reduce the residual tensile stresses. These features can reduce the risk of delayed cracking. 


Shielding Gases:


Since the cellulosic electrodes may bear moisture and thus the hydrogen, experts suggest that you should use the baked electrodes to reduce the possibility of cracking of your welded material. 


Rust And Scale Removal:


Before you start welding, it is always advisable that you clean the joints to remove the rust and scale. Because moisture or grease on the metal usually bears hydrogen, the number one reason for delayed cracking.


Fusion:


Perfect fusion reinforces by merging the weld metal with the weld toes. Since stress concentration can lead to delayed cracking, reinforcement reduces the concentration and help to avoid cracking.


Conclusion:


For good quality welding, you should exercise the practices like proper cleaning of the joint, pre-heating of joint, use of nickel & austenitic materials and use of multi-pass technique.

Stick Welding or Shielded Metal Arc Welding (SMAW) is a versatile and one of the most popular outdoor welding process. Unlike other types of welding like MIG and TIG, SMAW doesn’t require a gas cylinder. Rather it uses electricity for burning the stick like an electrode, and thus, wind can’t hinder your welding works. We offer you a complete guide on various aspects of stick welding. Let’s look into it!!


What is Stick Welding?


In stick welding, electricity passes through the metal electrode & the workpiece and high temperature melts the electrode down into the workpiece and it forms a weld pool. There is a flux layer cover around the electrode stick. Like shielding gas in TIG and MIG, this layer protects the weld pool from contamination of the environment. After the welding is over, you will find a layer of slag created by the flux on top of the weld head. So, you need to chip off and brush the slag down for a better output.


Advantages and Disadvantages of Stick Welding:


Advantages Disadvantages

1. Stick welding is economical since the electrode and the electricity used don’t incur any costs.

2. It is a portable solution as it doesn’t require any fire feeder or gas cylinder.

3. It is best for outdoor conditions.

4. If your workpiece is rusty, you can still weld on it.

5. Mastering stick welding is easier than other conventional methods. 

1. You have to operate it manually. There is no option for running mechanically or automatically.

2. The rate of deposited weld metal could be very high.

3. You need to be more skillful in comparison to its counterparts.

4. Huge spatter and slag require higher cleanup time and thereby decrease the efficiency.

5. It may not give you a quality output as TIG does.

  


Process of Stick Welding:


Stick welding is a famous and highly used technique in the industry. Its plain vanilla method has led the way to be the number one choice. It is feasible and favorable for a good number of applications. Particularly, for repair and maintenance works, stick welding is the perfect solution. You will find lots of use of SMAW for fabrication of metals like nickel, copper, steel, and chrome. 





In the process of passing electricity, stick welding generates a high level of heat that melts both the metal surface and the electrode and later becomes a joint when gets cooled. Soon after getting the electricity, flux of the electrode starts to erupt from the surface. It creates a layer of slag to cover the melted pool. 


Usually, stick welding requires a range of 15-40 volts. But depending on how much flux is getting used, you can fix the voltage level. For the smooth operation, you will require relatively 30-500 amperes of power. Irrespective of the range, you must a digital or regular control on the power source so that you can adjust the voltages to synchronize with the environment or requirement of the metal.   


What Do You need to Start Stick Welding?


Safety Equipment:


Although welding is very important, you must prioritize your safety. Use the welding helmet, safety glasses, welding jacket, welding gloves, leather apron, denim pants, and leather shoes, etc. that will protect you from heat, sparks, and ultraviolet rays. You need to ensure adequate ventilation or an exhaust system to remove the fumes emitted when you work indoor. 


Stick Welder:


To fulfilling your welding need, you must have a welder. Depending on your nature of use ad budget, you choose either a multipurpose welder or a normal stick welder that is much cheaper and easy to use.


Ground Clamp:


It is available with the welder and helps to clamp the stick welder and the workpiece.


Slag Removing Tools:


Stick welding produces slag after the flux around the electrode gets melted. To smoothen the welded surface, you can use a hammer to chip off the slag and then use a wired brush to scrub this up.


Electrode:


The electrode is one of the most vital parts of stick welding. Each electrode contains a four-digit number. The first two digits represent the minimum tensile strength, third digit indicates which position suits the electrode for welding, and the fourth digit tells about the type of coating used and the level of current required. For working on mild steel, E60 or E70 electrode should serve your purpose with strong weld. On the other hand, 6013 is a great choice for beginners.


Digit Type of Coating Weld Current

0 Cellulose Sodium DCEP

1 Cellulose Potassium AC, DCEP, DCEN

2 Titania Sodium AC, DCEN

3 Titania Potassium AC, DCEP, DCEN

4 Iron Powder Titania AC, DCEP, DCEN

5 Low Hydrogen Sodium DCEP

6 Low Hydrogen Potassium AC, DCEP

7 Iron Powder Iron Oxide AC, DCEP

8 Iron Powder Low Hydrogen AC, DCEP, DCEN


Safety Measures for Dealing With Common Mistakes in Stick Welding:


Moderation in Voltage:


The shape of the weld might get changed for the variation in voltage and amperes required. With a high current, you would experience a wider bead and distortion along the wed line for the spatter. With the low current, you would get a narrow bead and an inadequate penetration.


Weld Speed:


Weld speed is an important factor to keep in mind for getting an expected outcome. Higher speed may lead to irregular structure, and lower speed may cause a convex-shaped bead.


Slag and Weld Angle:


If the weld angle is not as per the recommended standard practice, it will disturb the slag for which you may not get the expected result. If you can remove the slag easily, it means a smooth and perfect completion of the welding process.


The Arc Length:


Arc length plays a crucial role in obtaining sound metallurgical structure and determining the quality of the weld bead. Increasing length leads to a higher voltage that results in widen weld and spatter. Lower length leads to lower voltage that causes a convex-shaped bead.


Conclusion:

What is TIG welding vs MIG welding?

What is TIG welding vs MIG welding?

 What is TIG welding vs MIG welding?

TIG welding so exact thus perfect, that more often than not, there is no tidy up when it's set. You don't need to pound it, smooth it, do anything with it. The welds with his TIG, yet in the event that he has a long hurry to do - 10 or15 feet to weld and the TIG is much slower than the MIG. He needs his welds to look like TIG welds when he's set, which implies he presumably needs to utilize his point processor to smooth the weld, yet he completes his work. You get short run, exceptionally specialized welds from the TIG welder and creation keeps running with the MIG welder. on the other hand, watt has worked with TIG his whole life. He loves the accuracy, the capacity to weld aluminum, stainless steel, and so on with a similar machine and similar gas. When he tries to MIG weld, it sounds so natural to simply pull the trigger and weld. He says that with steel that bodes well, however, he discovers utilizing MIG to weld aluminum is exceptionally troublesome. On the other hand, Watt gets a lot of inquiries on his Web website about welding aluminum with a MIG and a spool firearm. Individuals purchase a welder, say from a tool shop, goes home and welds steel flawlessly. At that point, he puts on a spool firearm on the MIG welder and thinks welding aluminum will be as simple. He says the spools are commonly little and they're normally utilizing 4043 wire and you can't push the wire through the machines rapidly enough.  The spool firearms that have the rollers in the machines and another set in the weapon itself to help pull the wire so you can do a 15-foot welding keep running with aluminum. Yet, the spool pull gun is practically an indistinguishable size from a spool firearm, it's huge and burdensome and it's exceptionally costly.

What is the difference between a MIG and TIG welder?

The significant distinction amongst MIG and TIG welding is that one procedure utilizes a ceaselessly sustaining wire MIG and the other you utilize long welding bars and gradually bolster them into the weld puddle TIG. MIG and TIG welding both utilize an electric curve to make the weld. MIG welding is an extremely basic and simple procedure to learn contrasted with figuring out how to TIG weld. The specialized names for these are metal inactive gas (MIG), and tungsten dormant gas TIG. If we point out the comparison of a difference then its look like:

A MIG welder works by utilizing a ceaselessly nourishing spool of welding wire that consumes, melts and breakers both the base and parent metals together. You can weld an assortment of materials, for example, mellow steel, stainless steel, and aluminum. A scope of material thicknesses can be welded from thin gauge sheet metal up to heavier auxiliary plates. 

TIG welding then again is all the more generally utilized for your more slender gage materials. Things that are made with this procedure are things like kitchen sinks and tool compartments. The greatest advantage is that you can get your shut down truly low and not blow through the metal. 

Pipe welding and other heavier undertakings can likewise be performed, you simply need a unit that is fit for putting out the measure of energy that you require. 

The principal contrast amongst MIG and TIG welding is that one technique utilizes a constantly bolstering anode and is a quick method for putting down welds. The other way is a considerably more fine and sensitive welding strategy.

The most adaptable machine is the TIG welder as you can weld various sorts of metals. The drawback is that it is moderate. For anyone needing to do some welding at home your better decision machine to purchase would need to be the wire nourishing MIG welder.

What is welding and what are the different types of welding?

Welding is a metal joining process that is utilized for joining at least two comparative metallic workpieces by the utilization of heat. It discovers its application in an extensive number of mechanical procedures. Welding should be possible either by softening and cementing metals or by the utilization of weight and warmth. The joint created by welding is called 'welded joint' or essentially 'weld'. A decent quality weld ought to have an indistinguishable quality from that of the parent metal. Many power sources can be utilized to perform welding. A portion of the conspicuous power sources utilized is an electric circular segment, gas fire, laser pillar, electron shaft, ultrasonic waves, electrical protection etc. The quality and lifetime of the weld can be enhanced by giving after-treatment to the weld. High-Frequency Impact Treatment is a case of after-treatment gave to welded joints to enhance their weakness quality. Filler metals may likewise be utilized to fortify the welded joint. The use of filler metal relies upon the kind of workpiece and the welding technique utilized. Welding can be utilized to deliver five primary joints. These joints can be sub-arranged. The five fundamental welded joints are recorded below these are: Lap Joint, Butt Joint, Tee Joint, Edge Joint, Corner Joint 


Now the answer to the question what are the types welding: Welding can be characterized by two primary sorts – Fusion welding and Pressure Welding. These two sorts have a substantial number of subtypes. The grouping of welding is given underneath: 

1. Combination Welding

A brief introduction to MIG welding can give the answer what is MIG Welder?

When you consider welding, MIG welding is most likely what rings a bell. MIG remains for metal idle gas. It's likewise alluded to GMAW or gas metal circular segment welding. It comprises of a spool of wire that is nourished, alongside an idle gas, through a spout to the weld zone. With an unimportant crush of a trigger, a dormant gas stream is begun alongside electric current and wire bolster. Curve shapes between the wire and the base material; the wire softens, however, is constantly encouraged through the spout adding to the base material, while the idle gas shields the liquid puddle from climatic debasements. MIG welding can likewise be utilized without the protecting gas on the off chance that you have a flux-cored wire; motion in the wire consumes as the weld advances, making a gas shield around the liquid weld puddle. 


The simplicity of MIG welding takes into account speedier and longer welds. The main thing that truly restricts to what extent a weld can be is the obligation cycle of the machine and the continuance of the welder, be it human or robot. As a result of its effortlessness MIG welding is utilized as a part of practically every industry. Nearly anything you can consider from autos and trucks, to cultivate hardware and pipelines, utilizes MIG welding. It's likewise staggeringly simple to computerize, influencing it to ideal for tedious, sequential construction system works. The muddled sounding welding firearm is provided by the welding machine by a heap of three things: a hose for the gas, a link for the power, and a hose that the wire is nourished through. It's critical to keep the supply lines as straight as conceivable in light of the fact that the wire can stall out in the feeder tube.



In this contest the answer to what is MIG welding and benefits we have given below: what is the Dynamics of MIG Welding?

MIG welding is an acronym for Metal Inert Gas Welding. This procedure is some of the time likewise alluded to as Gas Metal Arc Welding (GMAW). MIG Welding is utilized for aluminum and additionally different metals and can be programmed or automatic. 

In brief, the MIG Welding utilizes a wire that is associated with an immediate current source which goes about as a cathode and joins two bits of metal through consistent stream by utilization of a welding device or firearm. In the meantime the wire goes through the welding weapon, a stream of gas is likewise gone through the firearm with a specific end goal to keep airborne contaminants without a worry in the world of the welding zone. The inactive gas acts as a shield all through the procedure to fulfill this assignment. This framework was created in the mid-twentieth century and is by and large a significantly speedier welding framework than stick welding. 

Advantages of MIG Welding: MIG Welding takes into account the creation of longer and more nonstop welds in contrast with other customary strategies. Because of the gas which acts as a shield, it additionally delivers much cleaner and without splatter, welding comes about. In any case, the operation of a MIG Welder is very not the same as that of other conventional welders and may require diverse learning strategies. Because of the quick welding that the MIG procedure permits, it has likewise been connected to the utilization of welding steel. It is the main strategy for welding utilized today for cars and is additionally the main welding system in for all intents and purposes all businesses. Be that as it may, on account of the utilization of a latent gas MIG Welding can't be utilized outside. Since MIG Welding utilizes an electric bend, welders must wear a defensive dress and in addition eye security. Since the shield gas is by and large unstable, other natural precautionary measures must be taken. Restricting the measure of oxygen in the welding range is one such precautionary measure as is expelling burnable materials from the work territory. Understudies in a MIG welding preparing program take in these sorts of MIG welding tips to guard them. In the first place put into utilization in the 1940s MIG Welding has advanced into a greatly profitable and helpful apparatus for the modern generation. The speed and quality with which work can be created have additionally expanded its incentive in the work put. The mechanized framework has permitted work procedures to accelerate and take care of the demand for the things being provided.

Now to answer what is actually a MIG welding machine? Basically, The MIG welding machine is a generally straightforward one, requiring a power supply, either gas barrel or transition cored wire, a spool of filler wire, and welding firearm associated with different tubes and hoses. The weapon comprises of a trigger to begin everything, a gas diffuser that guides the gas to the weld region, a contact tip that the wire and electric current gone through, all encompassed by a copper spout that secures everything.

Types of MIG Welder and What is the best make of MIG welder?

Gas metal curve welding (GMAW), now and again alluded to by its subtypes metal inactive gas (MIG) welding or metal dynamic gas (MAG) welding, is a welding procedure in which an electric circular segment frames between a consumable wire terminal and the workpiece metal(s), which warms the workpiece metal, making them dissolve and join. Alongside the wire anode, a protecting gas encourages through the welding firearm, which shields the procedure from contaminants noticeable all around. The procedure can be self-loader or programmed. A steady voltage, the coordinate current power source is most regularly utilized with GMAW, yet consistent current frameworks, and in addition substituting current, can be utilized. There are four essential strategies for metal move in GMAW, called globular, shortcircuiting, shower, and beat splash, each of which has particular properties and comparing points of interest and confinements. 

Initially produced for welding aluminum and other non-ferrous materials in the 1940s, GMAW was soon connected to steels since it gave quicker welding time contrasted with other welding forms. The cost of idle gas restricted its utilization in steels until quite a long while later, when the utilization of semi-latent gasses, for example, carbon dioxide ended up noticeably normal. Advance improvements amid the 1960s gave the procedure greater flexibility and thus, it turned into a very utilized mechanical process. Today, GMAW is the most widely recognized modern welding process, favored for its adaptability, speed and the relative simplicity of adjusting the procedure to mechanical robotization. Not at all like welding forms that don't utilize a protecting gas, for example, protected metal bend welding, it is once in a while utilized outside or in different territories of air unpredictability. A related procedure, transition cored circular segment welding, regularly does not utilize a protecting gas, but rather utilizes an anode wire that is empty and loaded with flux core.
