Abstract
1331760 Welding by pressure THERMATOOL CORP 8 Oct 1970 [23 Dec 1969] 47873/70 Heading B3R In welding two metal portions, the portions are advanced through a welding zone the portions being spaced apart upstream of the welding zone and being brought together thereat, high frequency current is caused to flow along paths in the portions to and from the welding zone, the portions which are heated by the current are enclosed in an imperfectly sealed cavity disposed wholly upstream of the welding zone and protective fluid is supplied to the cavity to escape as a jet towards the welding zone to envelop the weld zone in a controlled atmosphere comprising said protective fluid. A stainless steel strip 10, Fig. 1, 2 formed into open tubular shape is heated by high frequency current e.g. 200-500 KHz supplied to the strip edges by conductive blocks 19, 20 and is passed through rolls 12, 13 to bring the heated edges together at the welding zone 18. An outer ceramic shoe 28 with a wedge shaped end carrying nylon shims 31 is arranged between the rolls 12, 13 and has a bottom surface contoured to the shape of the tube against which it is resiliently urged. A recess 37 above the spaced apart strip edges is provided in the shoe 28 to which the tubes 38, 38
