Stainless steel is a popular building material long heralded for its durability and substantial resistance to corrosion. Welding with this attractive metal does pose some unique challenges that need to be considered before launching into a project with stainless steel.The Pros, Cons and Best Ways of Welding Stainless Steel What are the types of rods use for welding stainless steel?What are the types of rods use for welding stainless steel?If you use a stick welder to work on stainless steel, use only stainless rods. If the rod's suffix ends with "-16" then use it with AC welders and if it ends with "-15" then it's for direct current reverse polarity use. Your strongest results will come from the "-15" rod but both will work very well.Reference bakersgas/weldmyworld/2011/02/24/tips-welding-stainless-s Guidelines For Pipe Welding - Miller - Welding Equipment
