摘　　要：实现钛与钢异种金属间的有效连接比较困难。为了探寻钛/钢的有效连接方法,在分析钛/钢异种材料的焊接性基础上,对钛/钢异种金属间的激光焊、电子束焊、激光-电弧复合焊等研究现状进行探讨。生成于接合界面的脆性金属间化合物是严重限制钛/钢异种金属接头性能的主要因素;选用合理的焊接工艺和添加适宜的中间层是实现钛/钢有效连接的重要途径。提出采用双层或多层金属的中间层来抑制界面金属间化合物生成是今后的研究方向。The effective joining between titanium and steel is relatively difficult. Based on the weldability between titanium and steel, the laser welding,electron beam welding,laser are hybrid welding technology of titanium/steel were introduced and analyzed in order to seek an effective joining method in this paper. The previous research results reveal that brittle intermetaUic compounds generate at the welding interface severely limit the performance of titanium/steel joint, and that choosing the reasonable welding technology and add appropriate interlayer is an important method to realize the joining between titanium and steel. Adopting double layer or multilayer metal layer to suppress interfacial intermetallic compound formation is a future research direction.
