Abstract

971,542. Welding by pressure. H. A. SCHLATTER A.G. Feb. 22, 1961 [Feb. 23, 1960], No. 6495/61. Heading B3R. A multipoint spot welder for making gridlike structures comprises a plurality of support members, at least one pair of electrodes on each support member, means for conducting workpieces between the pair of electrodes and means for operating the pairs of electrodes. The machine comprises a frame in which are mounted a number of narrow boxlike supports 3, each carrying a pair of hydraulic cylinders 4, 5 supporting the electrodes 1, 2. The supports 3 are arranged between upper and lower conductor rails 7, 8 and are slidable longitudinally relative thereto, the first, third &c. being connected to the upper rail and insulated from the lower while the second, fourth &c. are connected to the lower and insulated from the upper. A welding transformer is provided for each pair of electrodes, being connected to a conductor rail and to the adjacent electrode, e.g. a transformer 9 is connected to rail 7 and to a terminal 10 connected to the upper electrode, the lower electrode being connected to a terminal 13 in contact with the support member. Each pair of electrodes is fed from the same phase. A sleeve 6 is mounted centrally of each support member to guide the longitudinal rod to be welded to rods introduced transversely in the manufacture of concrete reinforcing mesh.
