Abstract

In joining a sleeve 26 to a tube 22, the sleeve is inserted within the tube and joined to the tube by means of an internal welding apparatus 28 which is inserted into the sleeve for bonding the sleeve to the tube. The portion of the sleeve to be joined is then sealed at 50, 64 and said sleeve portion is internally gaseously pressurized. Once the sleeve has been so pressurized, the bonding operation is initiated. In the case of gas-shielded arc welding, the molten weld pool under the arc is continuously driven by the internal pressure gradient toward the tube. In this manner the arc force is cushioned by the molten pool at all times thus preventing the weld arc from piercing through the sleeve. The welding apparatus may also be used to effect brazing of the sleeve to the tube, the sleeve externally carrying braze material.
