  • Patent number: 11203086
    Abstract: A laser welding method includes a pretreatment process and a welding process. At least one metal member of the plurality of metal members is formed from a metal-plated steel plate in which a base metal has been covered with a coating material that has a melting point lower than the base metal. In the pretreatment process, with the position of the first metal member in the in-plane direction fixed, processing is performed from the front surface of the first metal member to form on the back surface, a protrusion that bulges from the back surface. Then, in the welding process, the first metal member in which a protrusion has been formed is superposed on a second metal member with the protrusion therebetween while maintaining the position in the in-plane direction, and laser light is irradiated on the superposed region to weld the plurality of metal members to each other.
