Abstract

A laser welding method of the present invention is a laser welding method for irradiating with a laser beam a groove portionformed along a circumferential direction by butting axial end portions of cylindrical bodiestogether to weld the groove portion, the method comprising: a welding process Sof irradiating the groove portionwith the laser beam over the entire circumference to weld the groove portion; and a strain correction process Sof irradiating the groove portionwith the laser beam over the entire circumference, the laser beam having a heat input amount smaller than a heat input amount per unit area of the laser beam emitted in the welding process S
