MIG welding is a highly cost-effective type of welding that’s appropriate for repairing most commercial metals. First developed during the Second World War for weapon construction, it was eventually adopted by private industries, which recognized its potential to improve their manufacturing processes. Now, MIG welding rigs are used by DIY enthusiasts and professionals alike.

What Does “MIG” Mean?

“MIG” stands for metal inert gas, as the welding technique initially required an inert gas; however, carbon dioxide (which is not inert) was also discovered to work, leading some professionals to refer to the technique as Gas Metal Arc Welding. “GMAW,” however, doesn’t roll off the tongue quite as well as “MIG,” so welders are more likely to use the older acronym.

What Is the MIG Welding Process?

MIG welding requires a spool of steel wire, which comes out of a machine and through an MIG gun. The gun’s electrically charged contact tip activates when you pull the trigger, an action that melts the steel wire (think of it like a glue gun). The dripping molten steel forms a weld puddle, which attaches to the base metal.

Why Use MIG Welding?

MIG welding is popular for many reasons. To name a few, the continuous spool of steel wire allows workers to be more productive, as they rarely have to stop and gather new materials. It’s also extremely versatile, as it can be performed in a variety of positions, and it is appropriate for several metal types, including aluminum, mild steel, and stainless steel.
