ABSTRACT:
A method of manufacturing an externally clad tubular product employing a tubular host such as steel, including the steps of plating the external surface of the tubular host with a low melting point bonding metal alloy, assembling a tubular clad member, such as of nickel base alloy, over the plated tubular host, circumferentially welding one end of the cladding member to one end of the host member and welding the other ends in such a manner as to incorporate a metallic gas reservoir, thus forming a subassembly. The annular space formed in the subassembly between the interior of the cladding member and the exterior of the tubular host is evacuated of water vapor and oxygen. The evacuated subassembly is heated to about 1650.degree. to 2100.degree. F. thereby melting the bonding metal alloy, and the heated subassembly hot rolled to metallically bond the cladding member to the tubular host by means of the mechanism of liquid interface diffusion bonding.
