Abstract: PROBLEM TO BE SOLVED: To provide long-term usability and to prevent the occurrence of stress corrosion cracking by additionally improving the resistance to stress corrosion cracking. SOLUTION: Heat-affected zones 4 of a weld zone 3 formed by welding austenitic stainless steel piping 1 and 2 is heated by a laser heater 5 in water or air. In such a case, the inside surfaces of the piping 1 and 2 are cooled in the water or the air. The quality of the material of the heat-affected zones 4 is improved to the quality of the material having the resistance to the stress corrosion cracking by heating the outside surfaces. The piping 1 and 2 are then polished by a flap wheel so as to cover the heated outside surfaces. The residual stress of the tension produced during the heat treatment is made into compressive pressure by this polishing treatment, by which the resistance to the stress corrosion cracking can be additionally improved.
