Abstract
A laser welding method includes preliminarily heating an entire welding path by irradiating the entire welding path with a heating laser beam for a first predetermined time, the welding path being closed loop-shaped and formed at a boundary between two workpieces as welding objects, and performing scanning with a welding laser beam along the welding path while continuously performing the irradiation with the heating laser beam after the preliminary heating and terminating the irradiation with the welding laser beam after the welding laser beam goes around the welding path.
