Abstract
1,213,182. Welding by fusion. VYZKUMMY USTAV ZVARACSKY. 25 Jan., 1968 [28 Jan., 1967], No. 3930/68. Heading B3R. In electroslag welding a vertical seam the weld is backed by a cooling closure plate 18 pressed into engagement with the work by a pressure device which permits the plate 18 to pivot about a horizontal axis parallel to the plane of the work, the device comprising a main pressure mechanism 17 of known construction and an additional pressure mechanism 3 including a housing, an element for inducing a thrust force, a shaped insert for retaining the element in the housing, and a movable member associated with the closure plate 18 so that, in use, the thrust force of the mechanism 3 is such as to tend to tilt one end of the closure plate away from the surface of the workpiece towards which the plate is pressed by the main mechanism 17. As shown, the main pressure mechanism 17 bears on a lever 1 pivoted at 16 to the arm 8, the thrust being transmitted via a member 7 to the plate 18, and the additional pressure mechanism 3, having a movable, resiliently mounted rod 4 attached to one end of a lever 6 pivoted at 2 to the arm 1, is adjustable to exert an additional thrust force on the plate 18, whereby, as the plate moves along the work it may pivot slightly about the pin 2. In another embodiment (Fig. 2, not shown), the members (7) urging the plate (18) against the work, are mounted on a body (20) having two parts rotatable, mutually independently in vertical planes, about a pin (21) running horizontally and parallel to the plane of the work. The additional pressure mechanism (Fig. 5, not shown), comprises a nut (14) slideably mounted in the body (13) and threaded to the movable rod (4) and a helical spring (15) rigidly fixed by an insert (27) to one end of the body and secured at the other end to the nut (14). Adjustment is made by screwing up or unscrewing the knob (12) at one end of the movable rod (4).
