Abstract

850,558. Making electrical contacts; welding by pressure. ENGELHARD HANOVIA Inc. Jan. 27, 1959 [Jan. 28,1958], No. 2919/59. Classes 83 (2) and 83 (4). A flat electrical contact backing member has at least one welding projection on one face thereof, at least one welding projection on the other face thereof, the projections on one face being positioned substantially opposite the projections on the other face. Metal powder, wire or strip is formed into disc-like members I each having a welding projection 2 on one face and an opposed welding projection 3 on the other face. The discs 1 are fed in holes 11 of a graphite or ceramic plate 10 by vibration of the plate, the provision of projections on both sides of the discs making their orientation immaterial. A disc of precious metal or alloy or metal powder is placed over each disc 1 and melted so as to form, by surface-tension, a convex surface 13. The disc may be of silver and the disc 1 of a base metal flash coated with nickel, copper or silver, e.g. steel coated with nickel. The contact is then welded to a contact arm using the projection 3. A plurality of opposed projections 2 and 3 may be provided on the discs 1.
