Abstract

1,207,675. Making composite metal tubing, welding by fusion. INTERNATIONAL COMBUSTION (HOLDINGS) Ltd. 14 June, 1968 [16 March, 1967], No. 12317/67. Headings B3A and B3R. A method of making composite metal tubing comprises cladding by weld deposition either the outer or inner surfaces or both surfaces of a hollow metal ingot and then forming the latter into tubing. A hollow mild steel ingot is mounted for rotation about a horizontal axis and a welding head is supported on a carriage for reciprocation either parallel to or along the axis of the ingot. The filler wire is applied at an angle of 45 degrees, which angle is suitable for cladding the ingot with overlapping beads of austenitic stainless steel. The clad ingot is reduced to tubing by any suitable process and heat treated if necessary. The welding head, which is cooled, includes a tube for the filler wire, a purge tube delivering purge gas to the wire feed tube and a shield gas supply tube. The shield gas may be argon plus 5% oxygen.
