In a connection of two edges of areal parts which extend at least along one common section essentially parallel to one another, at least one retaining element (9,29,39,109) is arranged at the one edge which form-lockingly engages from behind, as viewed in the edge direction, in a recess (13,23,43,113) in the other edge. At least one projection (17,19,47,49,117,119) arranged laterally offset at the one edge in relation to the retaining element in the direction of the engagement from behind, abuts form-lockingly at the part with the recess essentially in the edge direction. To reliably secure together the parts, laser beam welding is used along the common sections of at least one of the retaining element and of the projection. <IMAGE> |
