ARC-WELDING DUPLEX STAINLESS-STEELS FOR MAXIMUM CORROSION-RESISTANCE

Arc welding ferritic-austenitic stainless steel can influence material corrosion behavior and, therefore, service performance. This article describes the main factors in formulating a welding procedure. Dependi ng on material composition, are energy should be between minimum and m aximum levels to promote austenite formation in the weld area without inducing intermetallic formation. Nitrogen loss should be minimized, a nd slight overalloying of the consumable is preferred.
