Which is better to weld stainless steel pipes by carbon dioxide welding or argon arc welding?

Obviously, argon arc welding is better. Considering the material of steel pipe, the deformation of stainless steel pipe after welding is obvious, and the welding temperature of gas shielded welding is high.

Not suitable for welding stainless steel pipes. Moreover, there are few stainless steel welding wires for gas shielded welding. If stainless steel pipes are to be welded, ordinary argon arc welding wires cannot be used. Use stainless steel welding wire.
