Tig Vs Mig For Sheet Metal

Generally speaking mig welding is more often recommended for ease of use.

Tig vs mig for sheet metal.

In some cases such as when welding high nickel content metals a helium and argon mixture is used. Tig tungsten inert gas welding uses long rods to fuse two metals directly together. Mig welding is used for non ferrous alloys but can be used for steel welding whereas tig welding can be used for any metal. This makes it preferable in applications where the welds will be visible.

While sheet metal is primarily a tig welding job there are times when it s handy to have an available mig welder to fuse sheet metal. Mig vs tig welding. Shielding gasses less commonly used in mig welding are helium argon and oxygen. Mig and tig welding both use an electric arc to create the weld.

These are reserved for specialty metals and aluminum. Learn why mig pulsed mig tig and pulsed tig are the ideal choices when welding sheet metal. Overall for really thick heavy duty welds mig welding is the go to option. It s one of the highest quality machines available and comes incredibly low priced.

Tig welding requires more practice than the mig welding because of the complexity and the tighter tolerances to be maintained while the mig welding is much more user friendly. Tig welding is also a better option for joining thinner material like sheet metal or fine gauge metal tubing. In comparison to mig welding tig welding produces equally strong but more finished looking welds. Tig welding almost always uses 100 percent argon gas to shield the weld puddle.

When welding thin metal the main objective is to avoid warping burn through and excessive heat affected zones while still ensuring the weld has enough mechanical strength for the application. Short circuit transfer mig short arc tig and pulsed tig welding processes provide the most control over the heat to address these challenges. The difference between the two is the way the arc is used.
