The subject of the present invention is a method for welding, using a laser beam (3), two thin coated metal sheets (1, 2) arranged edge to edge or slightly overlapping. The welding is performed in two stages, a first stage during which the two metal sheets (1, 2) are welded by the focused laser beam (3) moving over the junction plane (5) of the said metal sheets to be welded, and a second stage during which the non-focused laser beam (3) moves over the junction plane (5) of the welded metal sheets (1, 2). <IMAGE> |
