  • Publication number: 20170259380
    Abstract: Irradiation with a laser beam is started at a welding start position of two members that are stacked together, and the output of the laser beam is set so that spatter is not generated. After the start of the irradiation, the output of the laser beam is gradually increased so that a penetration depth from an irradiated edge to a deeper location between abutting surfaces of the two members falls within a predetermined penetration depth range while the laser beam is not moved. After the output of the laser beam is gradually increased, the laser beam is moved toward a welding end position so that the penetration depth is maintained within the penetration depth range.
