Abstract

PURPOSE:To prevent the segregation of a weld metal, to fine the crystal grains and to improve the material quality thereof by welding an austenitic stainless steel and imparting specific deforming work to the solidified weld metal in the temp. region above the recrystallization temp. CONSTITUTION:The weld metal is imparted >=10% strain working while the weld metal is in the temp. region above the recrystallization temp. thereof after solidification in welding of the austenitic stainless steel. The weld metal is otherwise imparted >=5% strain working in the temp. region below the recrystallization temp. and is then heated to the recrystallization temp. or above. The above-mentioned strain working is preferably applied uniformly to the weld metal part by means such as peening. Random and fine crystal grains of the weld metal are thereby formed and the microsegregation is prevented, by which the weld metal having the excellent corrosion resistance and mechanical properties is obtd.
