METHOD OF WELDING TITANIUM ALLOY PARTS WITH TITANIUM INSERT

摘要

A method of welding opposite end surfaces of two alphabeta type titanium alloy parts by a high energy-density welding process comprising closely interposing an insert member between said end surfaces of the two titanium alloy parts, the material of said insert member consisting of 0 to 3% by weight of aluminium and incidental impurities, the balance being titanium. The obtained weld joints are subjected to a post-welding heat treatment which is a combination of a solid solution heat treatment and a subsequent aging treatment.
