Abstract

1,115,483. Welding by pressure. L. & C. STEINMULLER G.m.b.H. 11 June, 1965 [12 June, 1964], No. 24860/65. Heading B3R. In a method of machine welding longitudinally finned tubes, comprising arranging two tubes 1, 2, in axial alignment with an end of one tube abutting an end of the other tube, the fins on each tube are cut back a distance 5 from the abutting ends and then the tubes are welded together by flash butt welding. The cut-back 5 on each tube is arranged to correspond to half the total of the length of material that burns away during flashing plus the reduction in length due to upsetting. Quadrants 6, 7, 16 and 17 out out of the fins accommodate the upset material and the ends of the fins are slightly fused together.
