The flux-cored welding wire is intended to inert-gas shielded fusion welding of titanium and its alloys and includes a metal coating or tubular casting of titanium or its alloys and a powder flux core containing (per cent by weight):
Baf2 -- 5 to 10,
Fluoride of a rare-earth element -- 18 to 20,
Caf2 -- 40 to 50,
Srf2 -- the rest,
The ratio of the weight content of the powder flux to the total weight content of titanium in the wire being from 0.3: 1 to 1: 1.
