Title: METHOD FOR LASER WELDING DESIGN MEMBER
Abstract:
A method for laser welding a design member (10) that has a hairline, in which a component (20) is joined to the rear side (10b) of the design member (10), wherein the laser welding method has: a positioning step for positioning a component at the position where the component (20) is joined on the rear side (10b) of the design member (10); a movement start step in which a laser head starts to be moved; a welding step in which the rear-side of the design member (10) is irradiated, along the hairline, with a laser beam (32) from the laser head (30), and the component (20) is welded; and a movement-stopping step for stopping the movement of the laser head.
