ER2209 welding wire is used in this paper to conduct GMAW - P welding test on UNS S32101 duplex stainless steel so as to research the welding performance of UNS S32101 duplex stainless steel,based on AWS standards and the technical requirements for advanced pressurized water reactor of AP1000 module design. The results show that all parameters of mechanical property,ferrous con-tents,and intergranular corrosion of the welding joints meet the standard and technical requirements if proper welding materials,welding procedure parameters,energy input and interpass temperature are chosen.
