Abstract
A method for welding a first workpiece with a joining element, wherein the joining element and the first workpiece consist at least partially of a metal, includes moving the joining element relative to the first workpiece during welding and at the same time pressing the joining element against the first workpiece. This method for welding a joining element with a material permits a reliable firmly-bonded connection between joining element and workpiece, when the workpiece consists of a composite material or has low rigidity, and is achieved by generating an electrical current between workpiece and joining element during mechanical contact of the joining element with the first workpiece.
