Abstract

1475678 Welding by pressure WOODHOUSE & RIXSON Ltd 3 Sept 1974 [11 Sept 1973] 42713/73 Heading B3R In friction welding a cylindrical metal shaft S to a steel plate P to form a pivot pin for connecting excavator buckets, at least the shaft is formed with an annular projection 20 at which friction welding is to take place, the projection on the shaft being spaced inwardly from the periphery of the shaft and the parts are brought together under relative rotation and pressure to produce a weld flash wholly or substantially wholly located inwardly of the periphery of the shaft. If a very small amount of flash projects beyond the shaft periphery it may be removed by simple grinding. In one embodiment the face 18 of the plate is skimmed to produce a flat welding area, as in Fig. 4, but in a modification the plate may also be provided with an annular projection 24, Fig. 7. The finished pivot pin is passed through the apertured lugs of a pair of excavator buckets so that the head P sits in a recess in one where it is secured by a cotter pin.
