Abstract

While steel sheets, overlapping each other (W1, W2) are positioned and held by a holding mechanism (12), a first laser beam (L1) is applied to a heating region (P1) of the steel sheet (W1) to space the steel sheet (W1) from the other steel sheet (W2) by a predetermined distance. A second laser beam (L2) is applied to a welding region (P2) to weld the steel sheets (W1, W2) and is moved the welding direction in synchronism with the first base beam (L1). An amount of heat applied by the first laser beam (L1), a moving speed of the first laser beam (L1), and a focused spot diameter of the first laser beam (L1) are set to keep the sheet (W1) irradiated with the first laser beam (L1) in an unmelted state and plastically deform the sheet (W1).
