LASER WELDING METHOD |
摘要 |
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. |
