Abstract
A method for connecting shell parts (), which have been formed from sheet metal, for example by deep drawing. The shell parts () may be any desired workpieces of a chassis part in the form of semifinished items or other components that are suitable for a folded seam connection. For this, the shell parts must have edges which are arranged lying one against the other in the connecting position. The method according includes first arranging the shell parts () that are to be connected in a position envisaged for the shell parts () in the connected state. Subsequently, the edge () of the first shell part () is folded around the edge () of the second shell part (), so that a folded seam () is formed. After the folding operation, according to the invention the folded seam () is heated and subsequently once again pressed together. As a result, a positive and gap-free folded seam connection is achieved, with which the shell parts () are permanently firmly connected.
