Investigation on microstructure evolution and properties of duplex stainless steel joint multi-pass welded by using different methods

We investigated the microstructure, impact toughness, and pitting corrosion resistance of duplex stainless steel (DSS) welding joints fabricated by using gas tungsten arc welding (GTAW) and flux-cored arc welding (FCAW) with different shielding gas compositions. N2-supplemented shielding gas during...
