Abstract
PURPOSE: To provide a welded joing having superior stress corrosion crack resistance by limiting the carbon content of a steel at the welding portion treated with solid solution.
CONSTITUTION: Welding groove edge 2 is formed at a steel pipe 1 or the like of austenite stainless steel having less than 0.03% of carbon content (SUS304L, SUS304LN, SUS316L) for butt welding. Depositing metal 3 contains less than 0.03% of carbon content (D308L or D309MoL). The entire welded portion is treated with solid solution to thereby decompose and solidsolve chromium carbide occurred at the crystal boundary of welding heat affected portion 4 of the pipe 1. Since the welded joint thus treated contains low carbon content different from SUS304, it hardly lower its quality due to precipitation of chromium carbide even if it is used at a boiling water reactor operated at 300°C of operating temperature for long time to provide superior stress corrosion resistance.
