Abstract
1,252,062. Welding by pressure. CENTRE NATIONAL DE RECHERCHES METALLURGIQUES. 18 March, 1969 [21 March, 1968], No. 14033/69. Heading B3R. An electrode for resistance welding comprises a body of high electrical conductivity alloy, i.e. between 50% and 80% of the conductivity of pure copper, coated on its working surface, with a layer of metal or alloy, different from the alloy of the body, of high melting temperature, i.e. above 1000‹ C. The electrode which is for welding galvanized or lead-coated mild steel may be a spot or roller electrode. The body may be of a copper alloy whose conductivity is between 50% and 80% of that of pure copper and the layer may be tungsten, molybdenum or one of their alloys which may be deposited by a plasma torch. The electrode may be a one-piece spot-welding electrode coated on its working surface or may be as shown in the Figure in two parts 3, 4 held together by a threaded ring 5 with the coating 2 over the working surface which, as shown, extends only across part of the width of the part 4 or which may extend across the wide width of the part 4 which is then curved.
