    Abstract: Methods for resistance welding, resistance-welded assemblies, and vehicles including resistance-welded assemblies are provided. The method includes providing a workpiece stack-up including first and second workpieces and an intermediate material located between the faying surfaces thereof. At least one of the first workpiece and the second workpiece is formed of a first metal alloy with a first concentration of an alloying element, and the intermediate material is formed of a second metal alloy of the first metal and a second concentration of the alloying element that is less than the first concentration. The method includes bringing electrodes into contact with the workpieces, passing an electrical current therebetween to form a molten weld pool, and cooling the molten weld pool into a weld nugget that forms all or part of a weld joint between the workpieces and has a composition that is a mixture of the workpieces and the intermediate material.

    Abstract: An apparatus and method are provided for manufacturing an orthopedic prosthesis by resistance welding a porous metal layer of the orthopedic prosthesis onto an underlying metal substrate of the orthopedic prosthesis. The resistance welding process involves directing an electrical current through the porous layer and the substrate, which dissipates as heat to cause softening and/or melting of the materials, especially along the interface between the porous layer and the substrate. The softened and/or melted materials undergo metallurgical bonding at points of contact between the porous layer and the substrate to fixedly secure the porous layer onto the substrate.

    Abstract: Copper conductor members or other copper-base workpieces are welded using a suitable copper alloy material that is reactive with the joining surfaces of the copper members. The reactive metal material may be applied as a thin metal strip between assembled facing joining surfaces. The members are pressed together against the reactive material and heated. The combined pressure and heat enable the reactive material to react with facing workpiece material, to liquefy and remove oxides or the like that might inhibit the formation of a welded interface. The liquid, containing original reactive metal and byproducts, is squeezed from the interface of the workpieces to enable the formation of a solid-state weld between them without melting of un-reacted workpiece copper material.

    Abstract: A metal-reinforced layered composite includes at least one intermediate metal layer. The intermediate metal layer includes at least two at least partially overlapping metal foils which are joined to one another in an overlap region by at least one weld seam. There are no leakage channels and/or no continuous leakage channels at the weld seam of the metal foils in the longitudinal extent of the overlap region. At least one of the weld seams may have a course which at least at one point has a direction component at right angles to the longitudinal extent of the overlap region of the metal foils. The intermediate metal layer may be provided with at least one passage in the overlap region of the metal foils.
