ABSTRACT:
In a method for automated manufacture of wound electrical components by contacting thin insulated wires to terminal elements on the basis of laser welding, only the terminal element is melted by direct laser irradiation to form a welding spot at the location provided for the welding. The wire is subsequently embedded into the welding spot as soon as the welding spot has cooled to such an extent that the wire subsequently only melts superficially. During the course of continuous winding of winding carriers, the insulated winding wire is wound into the welding spot produced on the respective terminal element, and is thereby pressed by the winding tension into the melt which solidifies to form the welded connection.
