Abstract
A method and to a device are provided for the marginal connection of sheet metals (8,9), particularly of car body sheets in automobile construction. In the device (1) the edge of a first sheet metal (8) is crimped over the edge of the second sheet (9) to form a fold (10). The edges are pressed together and connected to each other by thermal joining. In the region of the fold (10), at least one connecting device (7) is attached for the laser optics of a laser welding unit. Subsequent to the folding operation the laser optics is introduced in the region of the connecting device (7). At least one weld point and/or a weld seam is produced in the fold region. The laser optics is removed from the connecting device (7) and optionally connected to further connecting devices (7), and after all necessary weld points or weld seams have been produced, the finished component is removed from the device (1).
