Abstract

1419078 Welding by pressure A WACK A COSSET and R BEZICOT 21 Dec 1972 [23 Dec 1971] 59124/72 Heading B3R An electric resistance spot welder for double spot welding comprises a transformer 10 clamped between an upper casing 11 and a lower casing 12 and having a primary winding for connection to a power source and a secondary winding connected to two welding heads 19, 20, each carrying a welding electrode 21, 22, each welding head being mounted on the piston-rod 23, 23a of a respective jack 24 and the jacks being removably mounted by means of a replaceable jack support 28 on the upper casing. In an embodiment the transformer 10 is clamped between the upper and lower casings 11, 12 by tie rods 13. The electrodes 19, 20 are connected to the secondary of the transformer by flexible leads 17, 18 and the ends of the jacks remote from the electrodes are secured by studs 25 and nuts 26 to oversize holes in a lower plate 27 of the jack support 28 bolted to a bracket 31 of the upper casing 11. The jacks may be adjusted relatively to the plate 27 and the support 28 may be replaced by one of a series of different supports including a shorter support for different positioning of the electrodes. The flexible lead connections may each be replaced by a liquid metal connection, the head carrying a hollow body rotatably and slidably mounted on a spigot extending from the secondary with the liquid metal provided between the spigot and the hollow body.
