Abstract:The effects of the technological parameters of forming, welding, cold rolling and annealing on the precision and quality of welding seam of rolled Ti-0.3Mo-0.8Ni alloy were studied. It was found that this alloy possesses good formability and weldability, and that the quality of the welding seam can be improved by twice cold rolling plus annealing. The properties and the precision of the welded rolled pipes reach those of the seamless pipes of same specifications.
Key words: welded rolled pipes Ti-0.3Mo-0.8Ni titanium alloy cold rolling annealing
