Abstract
The invention is a weld metal for welding of a titanium alloy member to a ferrous based alloy member as an intermediate transition zone between such members so as to overcome the metallurgical imcompatability of each such member, and which consists of a vanadium metal, titanium and iron and inconsequential amounts of brittle intermetallic compounds. The preferred weld metal is vanadium rich and contains no more than 50% combined weight of titanium and such a weld metal is produced in accordance with our invention by fusion welding, particularly capacitor discharge welding, which because of its inherent but heretofore unrecognized extremely fast quench or freeze rates will produce a fusion weld between these two metallurgically incompatible alloys which is free of brittle intermetallic compounds. It is also part of our invention that such a weld metal of the aforesaid composition will have independent use as a welding alloy, particularly when fabricated in sheet form.
