Abstract
Joining regions in sandwich sheets having a plastic core layer disposed between two metal cover layers are desirable for purposes of joining sandwich sheets to other components by, for instance, fasteners and/or welded joints. Methods and apparatuses for producing such joining regions in sandwich sheets allow for durably form-fitting and/or force-fitting joints between the sandwich sheets and other components. Some methods may involve displacing plastic material of the core layer of the sandwich sheet out of the region to be joined. A predetermined force may be exerted perpendicular to a surface of the region to be joined when the core layer of the sandwich sheet is heated so that the plastic material of the core layer is softened and at least partially displaced. In turn, the metal cover layers of the sandwich sheet may be brought into contact with one another in the region to be joined.
