The paper object of this proposal was the electron beam welding (EBW) and electron beam local heat treatment (EBLHT) of a titanium alloy sheet. A three-dimensional thermal-mechanical coupled finite element (FE) model is established based on the FE software, and its secondary development function. Electron beam scanning experiments were performed on an 8 mm thick TC4 titanium alloy sheet. The cross-sectional morphologies of the different fusion zones are obtained. Weld surface width and weld penetration are compared between experimental results and simulated data. The model analyzed the temperature distributions on the sheet during the EBW and EBLHT processes.
