  • Patent number: 4203020
    Abstract: A method for producing strong resistance-welded joints between wires and massive workpieces, especially welded joints between nickel-plated copper wires and steel workpieces. The melting of the nickel coating is insured by producing locally high temperatures and pressures, due to the special configuration of the surface of the workpiece. The work surface is provided with bulges or protrusions which cause a concentration of electrical current and electrode pressure.
