METALLURGICALLY BONDING DISSIMILAR TUBES AND CLAD METAL

摘要

A method of metallurgically joining clad metal sheets or dissimilar metal tubes using a connecting member clad metal sheet (24) or a connecting member clad metal tube (16) in which the clad metal (12) is the same or similar metal to the cladding metal layer of the clad sheet (24) or to one of the dissimilar tubes to be joined (20, 16) and is susceptible to bonding by welding. The underlying clad metal connecting member metal is a layer or tube (22) of a dissimilar metal which is susceptible to bonding by soldering.
