  • Multi-stage resistance welding of sandwich-type metal sheets
    Patent number: 10583516
    Abstract: Sandwich panels may include an intermediate thermoplastic layer disposed between two metallic cover layers. Some methods for welding a sandwich panel to a metallic component may involve heating a region of the sandwich panel with a preheating current so that the thermoplastic layer is softened and by compression of the cover layers is displaced from the welding region. A tack-welding current flowing between first and second welding electrodes may weld the cover layers together, and a welding current may be used to weld the metallic cover layers to the metallic component. In some cases, the first welding electrode may be in contact with one of the metallic cover layers, and the second welding electrode may be in contact with the metallic component. As a result, the sandwich panel may be joined to the metallic component in a short cycle time without blisters and faults arising in the sandwich component.

  • Method for producing a composite material, and a provisional composite
    Patent number: 10525669
    Abstract: A method for producing a composite material, particularly a steel composite material, may involve providing a first workpiece and a second workpiece, producing a bonded connection between said first and said second workpiece in order to form a provisional composite, and rolling said provisional composite in order to form the composite material. During the rolling, the bonded connection may be at least partially released, in the form of a predetermined breaking point. The rolling may be performed as hot rolling. Further, the method may involve substantially hermetically sealing the provisional composite by way of a sealant. The first and second work pieces, moreover, may be peripherally connected by way of the bonded connection along an edge area of a contact surface formed by the first and second work pieces.
