ABSTRACT:
A method of firmly jointing Ti-alloy members of various shapes such as pipes and rods by solid diffusion bonding. The members are butted and heated under pressure in a non-oxidizing atmosphere, while a Ti-layer is disposed at the interface of butting by either (1) inserting a sheet for bonding made of Ti having a thickness of 500 .mu.m or less between the butted faces, or (2) previously forming a Ti-layer for bonding having a thickness of 1 .mu.m or more on at least one of the butted faces by any method such as vapor deposition.
