What Is The MIG Welding in a Nutshell,

Before you buy the equipment for welding, you need to ask yourself what kind of welding you want? There are different welding machines, and most of them are good at joining metal pieces, but some are better than the rest. MIG welding will be the best option for both the beginner and pros. It is a universal option to work with because it is simple to use once you learn the basics about the working process of MIG welding. This article will sort out all of the confusion and will give you the fundamental ideas about what is the MIG welding?

What Is The MIG Welding, What does MIG mean?

The full form of MIG is metal inert gas welding. It is also known as GMAW welding. GMAW means gas metal arc welding, which is the technical name for it. Some people call it wire welding too. It is a process of arc welding to joint two base materials together to form one single object.

Basic working procedure

A thin wire acts as the electrode, which is fed continuously through the welding gun by pulling the trigger. It comes out from the nozzle of the welding gun. When the trigger is pulled, it also supplies welding current and exhales shielding gas, which protects the weld pool from contamination. An electric arc is formed between your working piece and the wire once you start working with it. It heats both of the metal pieces above their melting point, causing them to melt and later solidify to make a single piece. The nozzle of the machine also releases shielding gas while working. It is the answer to what is MIG welding.

Advantage

MIG welding is a versatile form of welding to use for a wide variety of metals. It can quickly produce high-quality welds. The shielding gas is beneficial as it protects the arc and the weld pool. It prevents the reaction between the metals and other components in the air. it’s easy to learn and use. It can come in handy in a lot of ways. it has different switches to control various factors.

Disadvantage

Using it in a vertical position can be difficult due to the production of high heat. this is a complex equipment itself. It is challenging to use in an outdoor environment as shielding gas can be easily blown away due to the wind. It can be difficult to move the gas cylinder. Proper care must be taken. It has fast cooling rates. Sometimes it can get hard enough to get the gun in the right places.

Switches

In MIG welding, all the machine controls are placed on the machine itself. One can control the polarity, voltage, and wire speed. It has several different heat settings, which helps you to set the right power to have deep welds with good penetration. Else you might struggle to get the correct heat settings. You can also control the speed of the wire. The gas is stored in the cylinder. A device called a regulator can control its pressure. The on and off switch for the machine is the trigger on the gun.

Equipment

MIG welding machine consists of the following equipment-

  • Welding gun
  • Wire drive system
  • Power supply
  • Shielding gas supply
  • Wire drive system

Some welding machines can have a source of cooling water to reduce the heat of the machine. MIG rod oven can be used for the proper storage of wires. Before starting, take the equipment preparation. Check your cables and tension. Set gas flow and polarity for electrodes. Keep your area of welding neat and clean to avoid unwanted accidents.

Conclusion

Using a MIG welding process might seem complicated at the initial stage. But it gets easier once you gain basic knowledge about what is the MIG welding. It is a useful element to have. One can control the polarity, wire speed, and voltage using these switches. There are different MIG welding techniques. Figure out which is going to work for you. Before starting your work, make sure to have the proper safety apparel.
