Abstract
900,201. Making tubes; welding by fusion. HAZEN, F. DE F. April 6, 1960, No. 12128/60. Classes 83 (2) and 83 (4). In making welded seam tubing, a preformed sheet metal tube blank is held with its edges abutted under external pressure, the pressure being applied uniformly over the edges and over the full length of the tube blank, and the edges are arc welded and maintained under pressure until the weld is cooled. A sheared stainless steel sheet is preformed between dies to form a tube blank for a furnace recuperator and this blank is placed between dies 1, 2, the die 2 being secured to the frame 3 and die 1 secured to a beam 22 having cups 19 loosely receiving' the heads 18 of hydraulic pistons 17. The pistons are then actuated to bring the edges of the blank together in parallel relation, a bottom electrode 34, Fig. 8, being carried on a holder 39 spaced from a similar member by an inflatable rubber hose 40. The edges are welded by an arc welding electrode 33 and the pressure on the tube is maintained until the fused metal has cooled so that the tube does not distort or the joint open. The pressure on the edges may be 6.6 tons per square inch.
