AWS D10.18M/D10.18 – Guide for Welding Ferritic / Austenitic Duplex Stainless Steel Piping and Tubing

The ferritic/austenitic duplex stainless steels (DSSs) discussed in AWS D10.18M/D10.18:2018 have proven to be weldableusing proper welding procedures. The processes GTAW, GMAW (includes all transfer modes), SMAW, FCAW, andSAW have all been used with success on these alloys. Automatic and mechanized welding such as orbital welding withthe GTAW, GMAW, and FCAW processes have also been used with success on duplex alloys. Manual welders thathave experience with austenitic stainless steels should be able to apply many of the techniques they have learned fromthese alloys to the welding of duplex stainless steels, while of course keeping in mind the exceptions to be noted withinthis document.
