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