WELDING WIRE FROM TITANIUM ALLOYS Russian patent published in 2020 - IPC B23K35/32 C22C14/00 

FIELD: manufacturing technology; chemistry.

SUBSTANCE: invention can be used in production of filler materials for arc welding in medium of inert gases of high-strength (α+β) and pseudo-β-titanium alloys intended for use as high-strength structural high-tech material for making shipbuilding, aircraft and space equipment, as well as power plants. Welding wire contains aluminum, vanadium, molybdenum, zirconium, chromium and titanium, as well as limited content of impurities at following ratio of components, wt%: aluminum 3.5–4.5; vanadium 1.5–2.5; molybdenum 1.5–2.5; zirconium 1.0–2.0; chromium 0.5–0.7; carbon not more than 0.05; oxygen not more than 0.12; nitrogen not more than 0.03; hydrogen is not more than 0.003; titanium – the rest.

EFFECT: technical result is improved strength characteristics of weld metal (up to 973 MPa) while maintaining plasticity characteristics.
