The invention relates to a method for joining a composite sheet to a metallic substrate, wherein the composite sheet has at least one metallic top layer and at least one non-metallic layer which consists of a plastic material, wherein an opening is introduced into the composite sheet, and wherein at least one joining element is provided which is inserted into the opening of the composite sheet. A method for joining a composite sheet to a metallic substrate with process reliability and of specifying a corresponding structure is achieved by forming the joining element as a metallic sleeve, wherein the metallic sleeve is deformed, so that it joins together with the composite sheet in a form-fit and force-fit manner, and wherein the metallic sleeve is firmly bonded to the substrate with the end pointing towards the substrate using a filler material, wherein the filler material is arranged inside the sleeve.

Method for joining a composite sheet to a metallic substrate

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.
