The final purpose of this study is to establish the technology which repairs stress corrosion cracking (SCC) of overlaying of Inconel 182, which has been used as the material of the nuclear power plants and chemical plants by laser surface melting (LSM). In this study, the intergranular cracking/intergranular stress corrosion cracking (IGC/IGSCC) sensitivity was evaluated by the Streicher test and the Open Bend Beam (OBB) test. The parameters of LSM were laser power, traveling speed, defocus length and lapping rate of weld bead. The SCC, which occurred on the surface of overlaying of Inconel 182, was sealed by LSM and also the SCC sensitivity in remelted area remarkably improved in low heat input. LSM was considered as a useful method for repairing SCC in overlaying of Inconel 182.
