  • Publication number: 20200112236
    Abstract: A laser welding method for a stator coil forms an abutting surface by abutting a side face of a first lead portion of a first rectangular wire to a side face of a second lead portion of a second rectangular wire. A laser beam is focused on a position more inward than a surface of an upper end of the abutting face between the first lead portion and the second lead portion, and the laser beam is moved in a helical loop on the upper end of the abutting face between the first lead portion and the second portion so as to melt the conductor wires to form a molten pool. The molten pool is then moved along the abutting face while the molten pool is continuously formed.
