Short answer: Stainless welding consumables are matched to the base: 308L for 304, 316L for 316, 309L for dissimilar joints and 2209 for duplex, and low carbon grades avoid sensitization; supply in our Welding Wire Supplier ve Welding Electrode Supplier pages and the process in our How to Weld Stainless Steel guide.
At a Glance
Match Consumable to Base
The filler should overmatch the base alloy so the weld keeps corrosion resistance, with the base grades in our Stainless Steel Buyers Guide and supply in our Stainless Steel Supplier page.
Why Low Carbon (L)
308L and 316L keep carbon low to stop chromium carbide precipitation and intergranular corrosion after heating, with the corrosion link in our Surface Treatment Guide.
Dissimilar and Duplex
309L bridges carbon to stainless and 2209 welds 2205 duplex, with the joint detail in our Dissimilar Metal Welding Guide.
Quality and Certification
Confirm ferrite control and chemistry with our Quality Inspection Guide and MTC per our Mill Test Certificate Guide.
