Mig welding is a wire feed welding process where you use a mig welder.This would have to be the most used welding process in the world today. Using a welding gun, a power source, shielding gas and a constant feed of welding wire it's fast, simple and easy to do. It is the most cost effective and efficient way to weld. 

The technical name for "MIG welding" is actually Gas Metal Arc Welding (GMAW). You need to use a welding gas to shield the welding puddle and arc. Depending on the type of gas you use, either carbon dioxide or argon, then it can also be called "MAG welding".

So what is the difference? MIG welding is abbreviated for the phrase Metal Inert Gas, and MAG is abbreviated as Metal Active Gas. Some shielding gases mainly carbon dioxide and oxygen will react with the welding arc and puddle and help make the weld. So these are called active gases. But gases like argon and helium do not have any effect on the actual welding arc and therefore that's why they are called inert gases.

It is much faster than TIG or Stick welding and it can be adapted to robots and used in high end production facilities where part after part is repetitively manufactured.
