Abstract: Beam-shaping laser optics are provided with a lens field (28) which comprises a plurality of first lenses (32) which are configured and arranged next to one another such that the plurality of first lenses (32) effect a beam shaping in a first direction (y) normal to an optical axis (x), as well as with an individual second lens (30) which is configured such that the individual second lens (30) effects a beam shaping in a second direction (z) normal to the optical axis as well (x) as well as the first direction (y). The lens field (28) and the second lens (30) are arranged in a beam path (12) one after the other along the optical axis (x). A laser system is provided with such beam optics.

Abstract: A method for producing attached parts for a motor vehicle, for example doors, dampers, mudguards formed by internal (1) and external (2) sheets. The external sheet (2) is inward bent in the visible areas of the door or attached part, the sheet edges being practically parallel to the plane of attached parts in the invisible (not apparently visible) areas of the door or attached part. The internal sheet (1) is pushed against the external sheet (2) in a flanged area in such a way that a small accurately defined gap for laser welding is produced. The internal (1) and external (2) sheets are welded to each other in the form of an overlap joint in the opposite invisible areas, thereby compensating tolerances.

Abstract: A method provides for joining an outer sheet and an inner sheet, in particular of an attachment part of a motor vehicle body. On the visible sides of an attachment part, a welding or brazing seam is produced between a fold of an outer sheet and an inner sheet. The outer sheet is held in a bed, and the inner sheet is pressed against the fold on an inner side thus forming a joining groove. To ensure that during beam welding or beam grazing the inner sheet is held in position on the fold, it is prevented from moving away without clamping by stops on an outer side. These stops are disposed in a row along the welding or brazing seam and in dependence upon the progress of the joining procedure can be moved individually out of a path of a welding or brazing head.
