Tig Vs Mig For Sheet Metal

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.

Tig vs mig for sheet metal. Overall for really thick heavy duty welds mig welding is the go to option. In some cases such as when welding high nickel content metals a helium and argon mixture is used. Generally speaking mig welding is more often recommended for ease of use. Shielding gasses less commonly used in mig welding are helium argon and oxygen.

Tig tungsten inert gas welding uses long rods to fuse two metals directly together. Tig welding almost always uses 100 percent argon gas to shield the weld puddle. The difference between the two is the way the arc is used. This makes it preferable in applications where the welds will be visible.

In comparison to mig welding tig welding produces equally strong but more finished looking welds. The hobart handler 140 mig is the best affordable mig welder for sheet metal. Mig vs tig welding. Mig and tig welding both use an electric arc to create the weld.

It s one of the highest quality machines available and comes incredibly low priced. For thinner pieces of metal tig welding tends to be the more effective solution. Mig welding is used for non ferrous alloys but can be used for steel welding whereas tig welding can be used for any metal. Tig welding is also a better option for joining thinner material like sheet metal or fine gauge metal tubing.

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. 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.
