摘要
Abstract
The nuclear power reactor pressure vessel(RPV)is one of the core equipments in a nuclear power plant(NPP),and its safety and reliability are vital to the operation of the plant.The fabrication of RPV involves the dissimilar metal weld-ing of low-alloy steel to austenitic stainless steel.This paper discusses the problems of organizational inhomogeneity,el-emental diffusion,and stress corrosion cracking that exist in this welding.From the selection and optimization of welding filler materials,as well as the possible application of welding methods,post-weld heat treatment,process control,and other directions to discuss possible solutions to welding problems and development directions.To provide a reference for future re-search to improve the quality and reliability of such joints,thus ensuring the safe operation of NPPs.关键词
