Abstract
In this work, a girth weld of AISI 304 stainless steel pipes with a dimension of Φ89 mm × 250 mm × 14.5 mm was produced by laser beam welding. The microstructure was observed by optical microscopy. The microhardness test was carried out to study the mechanical properties of the welded joint. A slow strain rate test was performed to investigate the susceptibility to stress corrosion cracking (SCC) of the welded joint in the simulated pressurized water reactor environment. The results show that the values of microhardness in the weld and HAZ are close to those in the parent material. According to ultimate tensile strength-loss rate, elongation-loss rate and fractograph analysis, the welded joint has low susceptibility to SCC in the simulated pressurized water reactor environment.
