Abstract

1404129 Resistance welding contact assemblies LUCAS ELECTRICAL CO Ltd 19 Sept 1972 [6 Nov 1971] 51672/71 Heading B3R An electrical contact assembly, e.g. for a car distributor, is made by capacitor discharge electrical resistance welding a metal, e.g. tungsten, contact 2 to a steel (mild) backing plate 1 which has a nickel plate coating 3 at least in the vicinity of the weld. A capacitor discharge resistance welding machine may be employed rated at 1000 watt/sec. with a 4 inch air operated cylinder in the operating ranges of charging voltage between 950-1250 volts and cylinder feed pressure of 50-70 p.s.i.
