| Abstract: | The analytical calculation method was used to analyze three-dimensional temperature field formed in electronic beam welding (EBW) titanium alloy plates, which could consider the affects of keyhole of EBW. Through a large number of calculations, the effect of the computation parameters on the welding temperature was discussed. The manner and principle of determining the parameters was given. The calculatied results show that the method can not only calculate the shape of weld, but also the whole three-dimensional temperature field of EBW. It has the important applicable value for the engineering problems. |
