Abstract: Here is reviewed the development of high temperature titanium alloy welding at home and abroad. The welding characteristics of high temperature titanium alloy and the requirements for the consistency, uniformity and stability of the thermal strength, thermal stability and creep fatigue resistance of the welded joints of high temperature titanium alloy are summarized. The research status of technologies of flash butt welding, linear friction welding, electron beam welding and laser welding are introduced, and the future research direction of high temperature titanium alloy welding prospected.
