How To Weld Stainless Steel Wire. Gases for welding stainless steels. To weld the ferritic stainless steels filler metals should be used which match or exceed the Cr level of the base alloy.
The inert gas flow which protects the arc zone from the ambient air enables a very stable arc to be maintained. Stainless steel wire can be butt welded. Metal Inert Gas MIG welding also known as gas metal arc welding is effective in the joining of stainless steel wire and mesh.
But you will need to think about protection for your join as it will have mild steel mixed in.
MIG welding makes use of a shielding gas responsible for encouraging greater arcs and energy generation for a much stronger weld. Rods or coiled wire for automatic welding. However the MIG welding process which uses filler is most preferred when welding stainless steel to dissimilar metals such as mild steel. You can use the Tungsten Inert Gas TIG and Metal Inert Gas MIG.
