- the edge areas of the upper and lower sheet metal strip that meet at the joint are arranged in one plane, so that a gap for the application of a weld seam is only provided by the curvature of the edge area in the joint area.
- the weld seam can only be applied sealingly and reliably with increased effort, since the weld metal in the area of the joint during the manufacturing process in the liquid state tends to flow off due to the action of gravity, which negatively affects the quality of the weld seam. Complex measures must therefore often be taken in this area in order to produce a weld seam that is permanently reliable
