Abstract: Copper conductor members or other copper-based 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 foil strip between assembled facing joining surfaces. The members are pressed together against the reactive material and electrical resistance heated in forming the weld. Practices are adapted for forming many such welds in the pairs of facing ends of conductor bars or wires assembled, for example, in slots in a stator for a vehicle traction motor. Practices are disclosed for shaping and automated placement of suitably sized and shaped foils of reactive metal. Practices are also disclosed for use of a resistance welding tool in aligning and heating the many pairs of conductors to be welded.

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: Copper metal or metal alloy workpieces and/or aluminum metal or metal alloy workpieces are joined in a solid state weld by use of a reactive material placed, in a suitable form, at the joining surfaces. Joining surfaces of the workpieces are pressed against the interposed reactive material and heated. The reactive material alloys or reacts with the workpiece surfaces consuming some of the surface material in forming a liquid-containing reaction product comprising a low melting liquid that removes oxide films and other surface impediments to a welded bond across the interface. Further pressure is applied to expel the reaction product and to join the workpiece surfaces in a solid state weld bond.

Abstract: Weld faces of electrodes for resistance spot welding are formed with a suitable area of protrusions and/or intrusions. The size, shape, and elevation or depths of the protrusions or intrusions are determined for the formation of suitable spot welds in and between metal workpieces such as aluminum or steel panels for vehicle bodies. The protrusions or intrusions are also conceived and used to form an image on at least a visible surface of the welded article to produce an attractive appearance on the surface of the welded sheet.

Abstract: The workpiece-contacting surface of the spot welding electrode may be suitably modified to incorporate a desired shape or form, generally comprising a depressed region outlining a recognizable shape, to form aesthetically-pleasing or functional features in the surface of a workpiece during resistance spot welding. Methods for creating the desired form in the spot welding electrode including abrasion, upsetting, and electrical discharge machining are disclosed. Preferably the electrode face is shaped and subsequently redressed during welding operations at the welding station.
