Abstract

918,686. Making tubes and seams; welding by pressure; angular bending. WOGERBAUER, A. Dec. 8, 1960 [Dec. 10, 1959], No. 42345/60. Classes 83 (2) and 83 (4). In the continuous manufacture of a hollow component, e.g. a tube, a longitudinal edge of one section is brought together with a longitudinal edge of another section to form a notch and the sections are shaped by pressure exerted in the plane of the tip of the notch, the longitudinal edges are bent to be of sinusoidal form as they approach the notch to shorten the tip of the notch and the edges are heated to welding temperature in the zone where the tip of the notch is formed to weld them together. Two trough-shaped sections 1, Fig. 3, are guided by rollers 7-10 between rollers 4, 4 connected to the secondary 13, Fig. 6, of a transformer and flanges 12 on the sections are forced inwardly at the welding station by rollers 11, 11<SP>1</SP> above and below the sections to form a rectangular section tube, the notch 2 being curved and shortened. The distance a from the centre of the electrode rollers to the centre of the pressure rollers is equal to the width of the finished tube. The sections may form diamond, round or irregular cross-section tubes and the pressure rollers may be recessed as in Fig. 16, may be adjustable longitudinally and laterally of the tube and may be pivotable. The pressure rollers may be of ceramic or of insulated austenitic steel laminations. The final shaping of the tubes may be effected after welding. Specification 848,272 is referred to.
