Abstract
1,138,685. Welding by fusion. S.T.D. SERVICES Ltd. 17 Nov., 1966 [9 Nov., 1965], No. 47404/65. Heading B3R. A device supplying shielding gas to the inside of tubes being gas shielded arc welded comprises a supply pipe 15 having a port 22 through which the gas escapes and a pair of brushes 17, 18 mounted on the pipe 15 on opposite sides of the port 22 and each having bristles 21 engaging the wall of a tube 11 being welded. Such a device may be used to argon shielded arc weld the longitudinal seam of a tube 10. Argon is fed through the pipe 15. As the weld passes the zone 12 it is water-cooled. The device may be used in butt-welding tubes even if of different internal diameters. The bristles are of heat resistant resilient material such as stainless steel. The brush exposed to least heat may have nylon, copper or brass bristles. The internal gas pressure may be sufficient for the gas to support the weld metal.
