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

Oct 18, 2023

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. 

TIG vs. MIG Weld­ing — Unveil­ing the Distinctions

When it comes to weld­ing, pre­ci­sion and effi­cien­cy are para­mount con­sid­er­a­tions. The two pop­u­lar meth­ods, TIG (Tung­sten Inert Gas) and MIG (Met­al Inert Gas) weld­ing, may share a com­mon weld­ing” term, but their dif­fer­ences are sub­stan­tial. Mak­ing the right choice for your com­pa­ny’s weld­ing needs depends on fac­tors such as pre­ci­sion, set­up time, uti­liza­tion, and ini­tial costs. In this com­pre­hen­sive guide, we’ll explore the dis­tinc­tions between TIG and MIG weld­ing and help you deter­mine which method aligns best with your facil­i­ty’s requirements.

MIG Weld­ing: Stream­lin­ing Met­al Fusion

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.

MIG weld­ing, short for Met­al Inert Gas weld­ing, is a ver­sa­tile method for join­ing met­als. It oper­ates by com­bin­ing two pieces of met­al using a con­sum­able wire con­nect­ed to an elec­trode cur­rent. Dur­ing the weld­ing process, a wire pass­es through the weld­ing gun simul­ta­ne­ous­ly with an inert gas, often argon or a mix­ture of gas­es. The inert gas serves a cru­cial role in shield­ing the elec­trode and the weld­ing area from con­t­a­m­i­nants, pre­vent­ing oxi­da­tion and ensur­ing a clean, robust weld.

MIG weld­ing is favored for its effi­cien­cy and ease of use. It’s par­tic­u­lar­ly well-suit­ed for appli­ca­tions where speed and high pro­duc­tion rates are essen­tial. How­ev­er, the method may not be ide­al for projects requir­ing intri­cate welds or the high­est lev­els of precision.

TIG Weld­ing: Pre­ci­sion with Tung­sten Elegance

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.

TIG weld­ing, or Tung­sten Inert Gas weld­ing, takes pre­ci­sion to a whole new lev­el. This method uti­lizes a non-con­sum­able tung­sten elec­trode and an inert gas, typ­i­cal­ly argon, to weld two work­pieces togeth­er. Unlike MIG weld­ing, TIG weld­ing relies on the tung­sten elec­trode to pro­vide the elec­tri­cal cur­rent, but not the filler mate­r­i­al. While TIG weld­ing can incor­po­rate filler, it excels in cre­at­ing pre­cise, clean welds that don’t blur the bound­aries between the joined materials.

TIG weld­ing is often the choice for appli­ca­tions demand­ing utmost pre­ci­sion and con­trol, such as aero­space, auto­mo­tive, and artis­tic met­al­work. It’s the go-to method when weld aes­thet­ics and qual­i­ty are of para­mount importance.
