What's the Difference between TIG vs. MIG Welding?
MIG welding, or Metal Inert Gas welding, combines two pieces of metal together with a consumable wire connected to an electrode current. A wire passes through the welding gun at the same time as the inert gas. The inert gas protects the electrode from contaminants.
TIG welding, also known as Tungsten Inert Gas welding, uses nonconsumable tungsten, along with an inert gas, to weld two work pieces together. The tungsten electrode provides the electricity, but not the filler, for the welding process. While it can use filler, it sometimes creates a weld where one part melts into another.
