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.


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.
