  • Welding Stainless Steel - The Welders Warehouse Blog

    The general rule with Welding Stainless Steel is to weld it with either the same grade of Welding Rod, Tig Wire or Mig Wire, or a higher grade. So you could weld 304 Stainless Steel with a 308 or 316 Rod/Wire, but you shouldn't weld 316 with a 308 Rod/Wire. 308 and 316 grades of Welding Rod/Wire are often modified from the basic alloy.
