What is MIG?
MIG Welding stands for Metal Inert Gas welding. It is also called GMAW or the Gas Metal Arc Welding or even as Wire Welding. It has a thin electrode in the middle of the wire which is connected to a device through a welding gun or a torch. A welding current or a shielding gas is produced when the trigger of the welding gas is pulled. An electric arc is formed and heats metal at a temperature that is higher than the particular metal’s melting point. The metal inside the welding which is commonly called the filler metal and the metal that is being heated or the base metal, both melt and solidify as one. MIG welding is therefore very unique as it melts as it is being used. It is therefore, very aptly called a consumable electrode.
The wire electrode goes through something called a conduit liner before reaching the torch nozzle. It is then fed through the contact tip that goes through a gas diffuser. The gas diffuser contains shielding gas which leaves through the nozzle. The shielding gas is usually a mix of argon and carbon dioxide and it prevents the metals from reacting with atmospheric gases like oxygen when they melt. One interesting fact about MIG Welding is that the current must always pass in a circle. This means that the current flows from the machine to the nozzle to the work and back into the machine. A work led is usually used to complete the process by connecting the machine and the work.

Why use MIG?
1) Easy to use
The reason why most people prefer using MIG is because it is comparatively very easy to use and master. If you like to repair things on your own or do your own maintenance work, MIG is the welding that you should familiarize yourself with.
2) High Quality
MIG welding does not use flux. Therefore, the metal weld will not have any slag in them. This means that the weld is produced considerably faster and is in high quality as well. There are also many ways that MIG welding can come in handy, read this now and learn.
The flexibility comes in terms of the metal itself as well as in terms of the process of MIG. MIG welding is compatible with a lot of metals and alloys, giving it the ability to be very flexible in its usage. The metal of the MIG weld is also very flexible in terms of its nature as well.
4) More energy efficient
If you are trying to weld together two very thick pieces of metal together, ratemywelder.com, says that it is sure that a lot of energy will be required. This is where one should typically use MIG is apt of such welding and at the same time is very energy efficient.
