The invention discloses a method for repairing the performance of a titanium alloy electron beam welding joint, which comprises the following steps: firstly, carrying out a welding process on titanium alloy by using an electron beam welding machine, and then carrying out micro-arc oxidation treatment on a welded sample to obtain a layer of ceramic film on the whole sample. The micro-arc oxidation treatment is performed on the welded sample, so that the mechanical property and the corrosion resistance of the titanium alloy electron beam welding joint can be well repaired, and the stress corrosion resistance of the welding joint can be improved through the combined action of the micro-arc oxidation treatment and the titanium alloy electron beam welding joint. The method is environment-friendly in process and high in repeatability, the micro-arc oxidation operation is simple, and the prepared coating opens up a new way for improving the performance of a titanium alloy welding joint. 本发明公开了一种修复钛合金电子束焊接接头性能的方法，首先对
