Abstract
1,013,731. Welding by pressure. F. PEDLEY. July 24, 1962 [Aug. 10, 1961], No. 28909/61. Heading B3R. In projection welding together two tubes, the end of a first tube is machined to form a saddle to fit the other tube, the tubes are arranged at right angles with pointed projections on one tube engaging the other tube in point contact or with rods or wires between the tubes and current is supplied to melt the projections or the rods or wires to form spot welds. In joining tubes b, b<SP>1</SP> for furniture, the tube b<SP>1</SP> is supported in a jaw a<SP>1</SP> of a welding machine and the tube b machined to form a saddle provided with pyramidal projections b<SP>2</SP> is mounted in an upper jaw a. The tube b is lowered by a cylinder a<SP>5</SP> into contact with tube b<SP>1</SP> for, say, 5 cycles of a 50-cycle supply and current is supplied to melt the projection and a final pressure lasting, say, 20 cycles is applied. A hole may be formed in the tube b<SP>1</SP>, the saddle being welded around the sides thereof. In a modification, rods or wires c, Fig. 6, on a tape c<SP>1</SP> may be inserted between the surfaces to be welded to form the initial contact.
