TIG vs. MIG Welding - What's the Difference?

TIG and MIG welding are different processes to help accomplish a precise and accurate weld. They both have huge benefits on the production line. It is important to understand your company's precise needs and then decide on a TIG or MIG welding system.

TIG vs. MIG Welding - What's the Difference?


Though similar in the name, TIG and MIG welding have quite a few differences. Deciding which one is suitable for your company depends on the precision of weld required, time allocated for setup, utilization and initial cost. There are several benefits and fall backs to using TIG and MIG welding, depending on your facility's needs.

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 non-consumable 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.
