Abstract: A method of spot welding a workpiece stack-up that includes a steel workpiece and an aluminum alloy workpiece involves passing an electrical current through the workpieces and between welding electrodes that are constructed to affect the current density of the electrical current. The welding electrodes, more specifically, are constructed to render the density of the electrical current greater in the steel workpiece than in the aluminum alloy workpiece. This difference in current densities can be accomplished by passing, at least initially, the electrical current between a weld face of the welding electrode in contact with the steel workpiece and a perimeter region of a weld face of the welding electrode in contact with the aluminum alloy workpiece.

Abstract: A method of resistance spot welding a workpiece stack-up. The workpiece stack-up includes at least a steel workpiece and an aluminum workpiece. The method involves attaching a steel plate to the steel workpiece at a weld-site of the workpiece stack-up, passing electrical current between a first welding electrode and a second welding electrode at the weld-site, and terminating passage of electrical current between the first and second welding electrodes in order to form a weld joint. The steel plate serves to stiffen the weld joint.

Abstract: A method of joining workpieces includes the steps of bringing a first workpiece and a second workpiece together, induction heating a susceptor material, and pressing the workpieces together. Each workpiece may include a thermoplastic material, and the workpieces are brought together at a joint interface so that a protrusion of the first workpiece is aligned with a receptacle of the second workpiece. The susceptor material is in contact with the thermoplastic material of the first workpiece during heating such that the thermoplastic material of the first workpiece softens. The step of pressing is performed while the thermoplastic material of the first workpiece is softened, thereby reshaping the first workpiece where the susceptor material is in contact with the thermoplastic material of the first workpiece. The protrusion is deformed to form an interlock with the receptacle at the joint interface.

Abstract: A fused filament deposition head is employed for depositing filament materials on workpieces to join the workpieces together. The workpieces can be of an automotive application, aerospace application, or something else. The fused filament deposition head, in an example, has a feed end, a dispensing end, and a heater. The feed end introduces more than one filament in the fused filament deposition head, as demanded in the larger application. The dispensing end delivers materials of the filaments to the underlying workpieces. The materials are delivered together. The heater serves to heat the filaments as they travel through the fused filament deposition head. The filaments can include a filament having a core portion of liquid-crystal polymer material.

Abstract: A series of many electrical resistance spot welds is to be formed in members of an assembled, but un-joined, body that presents workpiece stack-ups of various combinations of metal workpieces including all aluminum workpieces, all steel workpieces, and a combination of aluminum and steel workpieces. A pair of spot welding electrodes, each with a specified weld face that includes oxide-disrupting features, is used to form the required numbers of aluminum-to-aluminum spot welds, aluminum-to-steel spot welds, and steel-to-steel spot welds. A predetermined sequence of forming the various spot welds may be specified for extending the number of spot welds that can be made before the weld faces must be restored. And, during at least one of the aluminum-to-steel spot welds, a cover is inserted between the weld face of one of the welding electrodes and a side of a workpiece stack-up that includes the adjacent aluminum and steel workpieces.

Abstract: A method of adhesive weld bonding a light metal workpiece and a steel workpiece is disclosed that includes applying a plurality of discrete adhesive ribbons to a faying surface of the light metal workpiece, the faying surface of the steel workpiece, or both faying surfaces, and then assembling the workpieces together to establish one or more adhesive zones between the faying surfaces of the light metal and steel workpieces and a plurality of adhesive free zones amongst the adhesive zone(s). The method further includes forming a resistance spot weld that bonds the the light metal workpiece and the steel workpiece together at a spot weld location within one of the adhesive free zones. The formed spot weld includes a weld joint contained within the light metal workpiece that bonds to the faying interface of the steel workpiece.
