Abstract: One or more ductile metal inserts may be selectively incorporated into articles of limited ductility, including metal castings and molded polymers. The inserts are positioned at joint locations for joining of the article to other articles using self-piercing riveting (SPR). The inserts are of suitable ductility, thickness and strength to receive and retain self-piercing rivets and enable a strong riveted joint between the article and a second article. In an embodiment the articles are magnesium alloy castings formed by any of sand casting, die casting and semi-solid metal casting. The chemical composition of the insert may be informed by the anticipated corrosive environment of the joint and the casting temperature of the magnesium alloy. For magnesium alloy castings which may be exposed to corrosive environments, aluminum alloy inserts are preferred.

Abstract: A workpiece stack-up that includes at least a steel workpiece and an aluminum-based workpiece can be resistance spot welded by a spot welding method in which the welding current is controlled to perform one or more stages of weld joint development. When it is desired to terminate weld current flow and to solidify a liquid weld pool into a weld nugget (of mostly aluminum-based composition), additional cooling is applied to the outer surface of the aluminum-based workpiece around the contact area of the spot welding electrode engaging the surface of the aluminum-based workpiece surface. The additional cooling is applied and controlled so as to increase the rate of solidification of the liquid aluminum-based material and to control the direction of solidification of the weld nugget to better confine impurities, and the like, originally in the melt, at the surface of the steel workpiece.

Abstract: A method of resistance spot welding a steel workpiece and an aluminum or aluminum alloy workpiece together includes several steps. In one step a workpiece stack-up is provided. The workpiece stack-up includes a steel workpiece and an aluminum or aluminum alloy workpiece. Another step involves providing a first welding electrode that confronts the aluminum workpiece, and providing a second welding electrode that confronts the steel workpiece. The first welding electrode has an electrode body and an insert that functions to limit or eliminate heat flux into the electrode body. Other steps of the method involve bringing the first and second welding electrodes into contact with opposite sides of the workpiece stack-up and resistance spot welding the stack-up.

Abstract: A method of laser welding aluminum alloy workpieces with dual laser beams arranged in a cross-beam orientation is disclosed. The method comprises directing dual laser beams, which include a first laser beam and a second laser beam, at and along a weld seam established between the aluminum alloy workpieces together with a filler wire. The first laser beam includes a first longitudinal axis and the second laser beam includes a second longitudinal axis. When arranged in the cross-beam orientation, a plane that intersects the first longitudinal axis and the second longitudinal axis of the first and second laser beams, respectively, forms a line where it meets the aluminum alloy workpieces that is oriented transverse to the weld seam.

Abstract: A system and method for stabilizing the molten pool in a laser welding operation by suppressing a laser-induced plume which occurs when zinc coated steels are laser welded. The plume is a result of vaporization of zinc, and the zinc vapor in the plume disturbs the molten pool and causes blowholes, spattering and porosity. The stabilization is achieved by applying a gas such as air through a nozzle to the weld area, where the gas has sufficient velocity and flow rate to blow the zinc vapor away from the molten pool. Dramatically improved weld quality results have been demonstrated. Configuration parameters which yield optimum results—including gas flow rate and velocity, and nozzle position and orientation relative to the laser impingement location on the steel—are disclosed.

Abstract: A method of resistance spot welding a steel workpiece and an aluminum or aluminum alloy (“aluminum”) workpiece together includes several steps. One step involves providing a workpiece stack-up with a steel workpiece and an aluminum workpiece. Another step involves attaching a cover over a weld face of a welding electrode. The cover is made of a metal material with an electrical resistivity that is greater than an electrical resistivity of a material of the welding electrode. Yet another step involves performing multiple individual resistance spot welds to the workpiece stack-up. The cover abuts the aluminum workpiece while the individual resistance spot welds are performed. And another step involves removing the cover from the welding electrode after the individual spot welds are performed.
