  • Patent number: 6528756
    Abstract: Prior to welding together two overlapped plated steel sheets 4 and 5 by laser lap welding that irradiates parts of the plated steel sheets (4, 5) extending on a weld line (Lw), slits (4b) are formed intermittently in the upper plated steel sheet (4) with a laser beam (L). Subsequently, a welding head (1) is moved along the weld line (Lw) while the upper plated steel sheet (4) is pressed against the lower plated steel sheet (5) by pressure rollers. Parts of the upper plated steel sheet (4) extending on the weld line (Lw) and not provided with the slits (4b) are irradiated with the laser beam to laser-weld the plated steel sheets (4, 5) together. A vapor of the component of the coating layers coating the joining surfaces (4a, 5a) of the plated steel sheets (4, 5) produced from the coating layers by the heat produced by the laser beam is discharged through the slits (4b).
