Ti6Al4V titanium alloy has been widely used in the fields of aircraft and chemical industy because of its high strength-to-weight ratio, superior corrosion resistance, creep resistance at high temperature, no magnetism and so on. Compared with the tradition welding method, the electron beam welding has some characteristics such as high energy density, small welding deformation and high efficiency, which has becomed one of advanced welding technique and important research directions.
