The invention discloses a titanium alloy for laser solid forming and laser shaping repairing, comprising the following components in percentage by weight: 3.6-5.0% of aluminium, 2.1-3.4% of vanadium and the balance of titanium, and the gross is not more than 100%. Compared with TC4 alloy in the prior art, the invention lowers the contents of aluminium and vanadium, and reduces the solid solution reinforcement effect of aluminium and vanadium in titanium; the strength of titanium alloy is lowered, plasticity is improved, and the strength and the plasticity of the titanium alloy are comparative to a TC4 alloy forged piece. The mechanical property of the laser deposition state of the titanium alloy is as follows: tensile strength is 910-980MPa, yield strength is 840-915MPa, elongation rate is 13-17%, and reduction of area is 39-50%. The invention not only can be used for laser shaping and repairing, but also can be used for high-energy beam processing technology, such as electron beam deposition shaping, electron beam overlaying, plasma overlaying and shaping and the like.
