What is MIG Welding Used For? Everything to Know

MIG welding is a type of welding that uses filler materials to create what appears on the surface to be a single piece. It’s often used for structural steel, stainless steel, aluminum, copper, and brass. 

 

MIG stands for Metal Inert Gas welding, which means that it doesn’t use fluxes to do its work. This method tends to produce solid welds with less distortion than other methods. This article will discuss what MIG welding is used for and what you need to get started.

 

What is MIG Welding? Understanding It Thoroughly

 

MIG welding is what’s known as a cold-weld process. This means that it doesn’t use fluxes to do its work, unlike the TIG method, which uses filler materials and shielding gases like argon or helium. The resulting weld looks very clean on the surface of the metal because it doesn’t have any slag issues like you get with stick welders.

 

Also, there aren’t any voids or pockets where air bubbles can be trapped underneath when trying to fill material together. This type of welding is used for all kinds of projects because it’s so versatile. It can be done on any alloy, including steel, stainless steel, aluminum, copper, and brass to name a few.

 

What Is MIG Welding Used For?

 

MIG welding is a common form of metal arc welding. The MIG stands for Metal Inert Gas, the gas used in the process being inert argon or sometimes carbon dioxide. MIG Welding uses an electric current to heat up and melt wire which becomes what joins pieces of metal together, and it’s also known as GMAW (Gas Metal Arc Welding).

 

This technique has been around since WWII but was initially developed by US Navy shipbuilders working on submarines that needed quick repairs at sea. It wasn’t until later that this became popular in the industry because you could create even solid welds without requiring any specialized equipment.

 

The torch system looks similar to what you might have seen people using when TIG welding, but it works very differently. For MIG welding, the wire goes through a separate part of the gun rather than being fed straight to the torch itself, which makes for more control over what you’re doing.

 

  • The power source used in MIG welding comes from an inverter plugged into any suitable 110V-volt socket and has its own earth connection. So no extra equipment or safety. procedures are required, other than what’s needed for everyday electrical work. It can also be used on all alloy materials like steel, stainless steel, aluminum, copper, and brass.
  • Even first-timers can easily do MIG welding.

 

MIG welding is a type of welding that uses filler materials to create what appears on the surface to be a single piece. It’s often used for structural steel, stainless steel, aluminum, copper, and brass because it doesn’t use fluxes, unlike TIG methods which do (and this makes it easier than traditional stick welding). 

 

This technique leaves behind clean-looking welds thanks to its lack of slag issues. At the same time, yield strength can make MIG welding jobs strong enough for nearly any job with little trouble for first-timers.

MIG Welding: The Basics For Mild Steel

 

MIG welding involves two steps:

 

  • Applying a filler material to the workpiece.
  • Melting and removing this filler material with an arc or electrical arc between a continuously fed consumable wire electrode and the metal being welded together.

 

The gas is inert because it doesn’t chemically combine with either the electrodes or a molten pool of metals that form at their connection point – like oil doesn’t mix into water. This gives us better control over these variables than if we weren’t using such an atmosphere.

 

Benefits of MIG Welding

 

  • Welding can be done on a variety of metals and alloys, including mild steel.

 

  • Low amperage makes for easy start-up and tutorial learning.

 

  • No need to purchase shielding gas. This is more economical than TIG welding in the long run since it isn’t an expensive consumable item that has to be continuously replaced when used with MIG wire electrode types.

 

  • It’s incredibly versatile because it uses electricity from alternating current (AC) or direct current (DC). This allows you to switch between different-sized jobs without having to invest in multiple machines! Plus, these two methods don’t require any expertise to use, which makes it even more beginner-friendly.

 

How to MIG Weld

 

Mig welding, also known as gas metal arc welding (GMAW) and inert metal gas (MIG), uses a continuous wire to deliver the shielding. Both workers and employers have widely accepted this type of process due to its high speed, durability, and flexibility. It can be done in both outdoor conditions (e.g., construction sites) and indoors (factories).

 

The gas metal arc welding process consists of feeding a continuous wire to an electrically-heated gun. 

 

This then melts the electrode’s filler material while shielding the weld area from atmospheric contamination and oxygen by adding a gas flow. This is what allows the process to be done in both indoor and outdoor conditions as it can be used with or without shielding gases.

 

The process can be done using either a constant voltage or a direct current power supply. The voltage remains steady throughout while the wire feeds automatically. It requires that both the gun and workpiece are positively connected to their respective poles of an electrical circuit to allow electric currents through to complete each weld cycle.

 

10 Reasons Why MIG Welding is Used

 

MIG welding is used in many industries, including automotive manufacturing and shipyards. It’s easy to learn what you need to know about the basics of MIG welding so that you can start your own projects at home or work. 

 

Here are some reasons why MIG welding is often chosen over other types of techniques:

 

1. MIG Welding Can Be Used With Different Filler Metals

 

The filler metal will give your metal project its strong points when using MIG welding. You may use bronze on the outside of a building to protect it from corrosion, or you may use steel on an interior staircase so that it feels warm to the touch. The filler metal will depend on what you need to get done with your project.

 

2. MIG Welding is Easy to Learn

 

Because MIG welding doesn’t require much time and effort, many beginners choose this type of welding when they’re learning a trade. If you’re new to welding, then you should consider using MIG as your starting point because it’s much easier than other types and will give you the skills you need for larger projects in the future.

 

3. You Can Use MIG Welding For Cutting or Piercing

 

There are many benefits of using MIG welding if you need to cut through metal. Not only is it fast, but MIG Welding will also produce less smoke than other types of techniques. It also makes little noise, so it’s great if you have neighbors close by or a crowded workshop.

 

You can use MIG welding to pierce through metal which is an excellent way to cut what you don’t need and keep what’s left intact. MIG welding is primarily used to cut delicate metals like aluminum. You can then go on to MIG weld the individual pieces together using this method.

 

4. MIG Welding is Used For Thin Sheet Metal

 

MIG welding is often used for thin sheet metal projects because it’s an effective way to join metals together. Moreover, it’s quick, and you can use it on different metals, including steel, stainless steel, and aluminum. 

 

Ideally, the metal sheet you’re working on should not be thicker than 1/2 inches. It’s a fast, easy-to-use method that can be used on different metals, including thin sheet metal.

 

5. MIG Welding Can Be Done in Tight Spaces With Less Distortion on The Weld

 

In industrial settings, MIG welding is used for many different types of metal projects, whether they’re industrial or home-based. This type of technique works so well in industrial spaces because it can be done in tight areas. It means that there isn’t much room to work with, but you’ll still get a high-quality weld every time.

 

MIG Welding also helps reduce distortion on the finished product by creating less heat and damaging what needs to stay intact as a part of your project at hand. What’s remarkable here is that what you’re looking for will have a much greater chance of being completed in an efficient manner, which means less time spent on the job and more money saved over time.

 

6. Welding Speed is Faster Than Other Techniques

 

One of the biggest reasons professionals use MIG Welding in most cases is because it can be done faster than other welding techniques. This technique also helps reduce spatter, which means that you don’t have to worry about dealing with waste materials afterward because what gets welded together will stay intact.

 

The MIG welding process uses gas-shielded equipment to create an electric arc between metal pieces. This action causes temperatures hot enough to melt the metal and form a weld joint. This can sometimes be done in minutes compared to what might take hours or longer with other processes, depending on what you’re trying to accomplish.

 

MIG welding uses shielding gas to protect against contamination by atmospheric oxygen for improved control of what’s being welded, what’s being kept intact, and what will be cut out of the project. In addition, MIG welding requires less cleaning with fewer sharp edges that need to be ground down after the process has been completed. 

 

It’s also a more efficient way to get what needs to be done finished because it can remove what doesn’t work while still keeping what does. If you want something reliable and effective, consider trying this type of equipment first. Lastly, MIG produces less spatter than TIG welding does.

 

7. Less Heat Input Means Less Distortion on Parts

 

For what it’s worth, MIG welding will help reduce heat input compared to other types of welding techniques. This means that the materials you’re using won’t end up being warped or damaged. If you’re working on something that has tight tolerances, then this technique makes sense considering the lesser risk involved with what gets done here.

 

8. Shielding Gas Doesn’t Need to be Changed as Often

 

If the project you’re working on is going to take a decent amount of time to accomplish, switching out these gases every now and again can become cumbersome. With MIG Welding, this isn’t something that you’ll have to worry about at any point. 

 

This type of technique also helps reduce spatter compared with other types of welding techniques.

 

9. MIG Welding Creates a More Attractive Finished Product

 

All in all, this type of process makes the finished product just look better overall when compared with other types of welding techniques. This means that what needs repaired or added to your project doesn’t leave anything to be desired. Instead, what gets welded together will be strong and sturdy so that it isn’t damaged.

 

10. Easy-to-Use Equipment That’s Relatively Inexpensive

 

MIG welders are simple to use, and many can be used with a basic 110-volt outlet. The equipment is relatively inexpensive compared with other types of welding, so it makes sense to try out MIG as a beginner.

 

MIG welders are simple to use, and many can be used with a basic 110-volt outlet. The equipment is relatively inexpensive compared with other types of welding, so it makes sense to try out MIG as a beginner. 

 

A common misconception about what the MIG welder costs is that they’re expensive pieces of machinery only for advanced or professional welders. Mig Welders start around $200 from some manufacturers on Amazon.

 

TIG vs MIG Welding – Which is Right For Me?

 

Basic Differences

 

1. Power Consumption

 

TIG welding uses Direct Current (DC), while MIG welding uses Alternating Current (AC). TIG welding melts a metal rod by sending electricity directly through it. In contrast, MIG welders melt the same rod with an electrical arc that jumps across two pieces of metal or another electrode wire fed into the work area.

 

2. Basic Functionality

 

This process creates intense heat where wires are melted together quickly rather than heating up slowly as TIG welding does. MIG welder machines are often smaller because they don’t require much power and can be handheld or strapped to a workbench. TIG welding machines are often much larger, as they need more power and the equipment itself is heavier.

 

3. Gases Used

 

TIG welders also use gas like helium, argon, or carbon dioxide (CO²) for shielding. In contrast, MIG welders don’t need any extra tools because of how it works with an electrical arc between two pieces of metal without worrying about using windy conditions that would affect TIG welder results.

 

4. What They’re For

 

MIG welders make clean, precise welds in less time than Tungsten Inert Gas (TIG) welding, making them perfect for working on projects such as car chassis suspensions where speed is vital. 

 

It’s important to remember that MIG welding can only join two pieces of metal together. In contrast, TIG welding is perfect for repairing automotive frames and other situations where you need an extremely clean weld to produce a strong bond.

 

Control and Quality

 

5. Control and Welding Performance 

 

TIG Welding provides better control over the quality of your finished product than MIG because it’s much easier to see exactly what you’re doing with TIG welding. 

 

With MIG welding, you may not be able to tell whether or not you’ve completely penetrated the base material unless it shoots out molten metal like in gas shielded flux core MIG welder applications. 

 

The filler wire used in MIG welding often looks different from the parent material, making visual identification difficult. In contrast, stainless steel rods look identical throughout all stages, making them more suitable for thin-sheet materials such as aluminum.

 

6. Precision

 

TIG welding is also more precise than MIG welding because it can be used to create very fine and intricate weld patterns without worrying about the heat distortion that would result from using an MIG welder. Another reason for this precision comes down to accuracy. 

 

MIG machines tend to lack an arc force control function, which means you’re at the mercy of gravity when working on thin or low-profile panels, whereas TIG welding makes completing your project much easier and faster with very little practice required.

 

7. Wires and Metals Used

 

MIG wire feeders can hold spools of wire instead of having them stick out like tungsten electrodes do to make things less complicated by not having any extra tools needed other than filling the gas bottle before starting your project. 

 

TIG welding requires the use of tungsten electrodes which need to be replaced constantly, making them more time-consuming and expensive than MIG wire feeders (spool gun).

 

8. Job Comfort

 

MIG welder machines are much easier to transport due to their smaller size, while TIG welding machines require an extra pair of hands or a cart for moving around your garage or work site. 

 

This is because they’re often heavier with larger transformers that increase the weight considerably versus MIG welders, which typically weigh less than 20 pounds. In contrast, TIG welding units can weigh up to 100 pounds depending on the wattage rating.

 

9. Overall Experience and Expectations

 

TIG Welding offers better control over heat input and metal deposition rates when compared to MIG because it has no power restrictions and is a more precise welding method. 

 

MIG welding is great for beginners because they don’t require as much power and give you the ability to control your wire feed speed with an easy turn of a knob on top of the machine. 

 

TIG welding requires plenty of practice before feeling comfortable. Still, it allows for greater precision when dealing with thin sheet metal materials such as aluminum. Aluminum can warp if heated too quickly from improper tungsten selection during MIG welding applications.

 

Tungsten electrodes must be replaced constantly due to bending or breaking off inside filler wires that cannot be seen clearly through smoke resulting from smoke MIG machines using flux core arc welding methods.

 

TIG Welding offers better control over heat input and metal deposition rates when compared to MIG because it has no power restrictions and is a more precise welding method.

 

10. Job Purpose

 

TIG welding is also used mainly for fabrication purposes. In contrast, MIG welding is often preferred by those who want to save money on material costs instead of spending the extra cash. 

 

MIG welder applications can create problems such as spatter, hot or cold lap joints, and porosity in your finished product if not done correctly. TIG welding applications are far more forgiving.

 

11. Overall Power and Efficiency

 

TIG welding is more precise than MIG welding because it can be used to create very fine and intricate weld patterns without worrying about the heat distortion that would result from using a MIG welder. Another reason for this precision comes down to accuracy. 

 

MIG machines tend to lack an arc force control function, which means you’re at the mercy of gravity when working on thin or low-profile panels, whereas TIG welding makes completing your project much easier and faster with very little practice required.

 

Conclusion

 

Welding can be challenging because it involves a complex process, but if you understand these principles then your chances at making successful projects increases tenfold! If you understand what is MIG welding used for, then you’re well on your way to becoming a welding pro.
