Tig Vs Mig For Sheet Metal

Shielding gasses less commonly used in mig welding are helium argon and oxygen.

Tig vs mig for sheet metal.

For thinner pieces of metal tig welding tends to be the more effective solution. This makes it preferable in applications where the welds will be visible. Mig and tig welding both use an electric arc to create the weld. Short circuit transfer mig short arc tig and pulsed tig welding processes provide the most control over the heat to address these challenges.

Mig vs tig welding. 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. Generally speaking mig welding is more often recommended for ease of use. In some cases such as when welding high nickel content metals a helium and argon mixture is used.

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 welding is used for non ferrous alloys but can be used for steel welding whereas tig welding can be used for any metal. It s one of the highest quality machines available and comes incredibly low priced. In comparison to mig welding tig welding produces equally strong but more finished looking welds.

Overall for really thick heavy duty welds mig welding is the go to option. Mig metal inert gas welding uses a feed wire that constantly moves through the gun to create the spark then melts to form the weld. These are reserved for specialty metals and aluminum. Tig welding is also a better option for joining thinner material like sheet metal or fine gauge metal tubing.

Tig welding almost always uses 100 percent argon gas to shield the weld puddle. 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.
