IPC: B23K11/00
Filed: 1958-05-14
Abstract: 906,540. Welding by pressure. RODD O'NEIL ENGINEERING CO. Ltd. June 15, 1959 [May 14, 1958], No. 15466/58. Class 83 (4). In welding a metal tube to another metal member the tube and member are arranged so that localized contact takes place between them and a flow of electricity is established through the portion of localized contact with the aid of an electrode having a channel shaped end extending radially toward the tube so that the walls of the channel make contact with the tube at two positions spaced from each other circumferentially around the tube with the floor of the channel spaced from the tube therebetween. In an embodiment a thin-walled tube 6, Fig. 2, to be welded to a parallel thin-walled tube 7 is deformed to form a projection 8 abutting the tube 7 and electrodes 9, 10 having legs 11, 11, 12, 12 straddling the tubes engage the tubes at diametrically opposite points 13, 14. The current flowing from one electrode to the other passes only around half the circumference of each tube. In a modification the legs of the electrodes are tapered to a point so forming a V section channel. Two metal tubes 21, 22, Fig. 7, crossing at an angle e.g. right angles, are welded without forming a projection on the tubes. A thin-walled tube 6, Fig. 6, with a projection 8 is welded to a flat plate 17, a shaped electrode 9a with an insert 9b of insulating material contacts the tube and a contact 18 engages the plate. A prior art method is described in which channel-shaped electrodes engage tubes over the whole channel surface.
