| Abstract: | Titanium alloy and niobium alloy are two kinds of alloy which have good performences, so these two alloys are widely used in such areas as aeronautics, spaceflight and nuclear industry. Numerical simulation of electric beam welding temperature field of Ti alloy and Nb alloy was studied by means of the ANSYS analysis software. Making use of two heat sources model, the method of model constructing and the technique of applying function load for different metal welding were studied. The weldabilities of the titanium alloy (7715 D) and the niobium alloy (C-103) were emphatically analyzed, adopting the method that the heat source offset to niobium's side to ensure the uniformity of the depth of welding penetration, and the optimum offset distance under different heat input was obtained during the welding of the titanium alloy and niobium alloy. |
