Abstract:
1. A joining method for joining sheet metal parts to a composite, the composite forming part of an outer shell of a vehicle when assembled onto the vehicle, in which method: a) a first sheet metal part having a first outer shell region and a first joining region which projects from the first outer shell region via a bent transition towards an inner side of the first sheet metal part and b) a second sheet metal part having a second outer shell region and a second joining region which projects from the second outer shell region towards an inner side of the second sheet metal part are fixed relative to each other in a joining position; c) and the sheet metal parts are connected to each other in the joining position by welding or soldering, thereby producing a welding or soldering seam such that the joining regions form a gap and abut each other along a strip, wherein the strip runs between the bent transition of the first sheet metal part and the welding or soldering seam; wherein d) a flange edge and a flange are shaped in the first joining region, the flange projecting along the flange edge from an adjacent area of the first joining region; e) the sheet metal parts are connected to each other such that the welding or soldering seam runs in the first joining region along or alongside the flange edge, and wherein f) the first sheet metal part is fixed in a first fixing tool for flanging and the second sheet metal part is fixed in a second fixing tool and said two sheet metal parts are fixed in the joining position by the first and second fixing tools without re-fixing said two sheet metal parts.
