Abstract

1,086,081. Making tubes; welding by pressure. F. KOCKS, [trading as FIRMA FRIEDRICH KOCKS]. Sept. 21, 1964 [Sept. 20, 1963], No. 38430/64. Headings B3A and B3R. In welding a strip to form a tube with a longitudinal or helical welded seam by electrical induction or resistance welding in which there is formed during welding at each surface of the tube either a weld flash alone or a weld flash together with an offset between the welded edges of the strip or a roof formation between the welded edges the edges of the strip are upset on each surface prior to welding and after welding a machining operation is effected to remove the weld flash on each surface of the tube, the amount of upset being such that during machining the thickness of the tube wall at the seam is not reduced below the thickness of the original strip. In a tube with a longitudinal seam the edges of the strip 11, Fig. 2, are upset at least by the height of the offset and after welding the flash 9, 10 is removed by tools 7, 8 to the lines 7a, 8a or 7b, 8b. In a tube with a longitudinal seam and a roof formation the strip is upset by a height at least equal to the height of the roof formation D, Fig. 4, and after welding the flash is removed by machining by tools 21, 22 to the lines 21a, 22a or 21b, 22b. A tube with a helical seam between chamfered edges, Fig. 6 (not shown) is also described.
