Abstract: A laser welding method of the present disclosure has a first step and a second step. In the first step, a first workpiece and a second workpiece are overlaid in a first machining region. In the second step, the first workpiece and the second workpiece are irradiated with laser beam in the first machining region while the laser beam is moved in a spiral path. Moreover, in the second step, the first workpiece and the second workpiece are melted by irradiation of the laser beam to form a liquid phase portion. Furthermore, in the second step, the laser beam is moved so that the liquid phase portion is not irradiated with the laser beam again.

Abstract: A laser welding method of the present disclosure includes the step of irradiating a workpiece with a laser beam in a helical shape along a weld part of the workpiece. The helical shape is a combination of a circular trajectory in which a laser beam is moved circularly, and a movement trajectory in which the laser beam is moved in a proceeding direction along the weld part. Furthermore, first energy of the laser beam moving so as to have a component of the proceeding direction in the circular trajectory is larger than second energy of the laser beam moving so as to have a component of an opposite direction to the proceeding direction in the circular trajectory.
