Gas Used For Mig Welding Stainless Steel. Gases such as high helium and argoncarbon mixture are ideal. A more affordable and common option for stainless steel is C2 which is composed of 98 percent argon to 2 percent carbon dioxide MIG Welding Gases nd.
There are also Argon with 25 Oxygen mixes but the most common is either the 25-3 Co2 or the ArHeCo2 mixes. It uses a continuous consumable solid wire electrode and an argon rich shielding gas for welds. Gases for pulsed arc welding are argon plus 1 oxygen the same as is used for spray arc welding.
In the United States welders mostly follow three methods for welding stainless steel ie.
Mixes with less than 100 Argon gas mixes can be used. Burning out the chrome counteracts stainless steels defining property which may in turn increase warranty costs. Even though most of the welding machine manufacturers have included a table of materials and voltage settings in the machine it is highly important for you to pick the right kind of gas and electrode wire to be used for MIG welding stainless steel. Although pure Argon gas cannot be used to weld stainless steel.
