中文摘要：

不锈钢和钛合金异种焊接在化工、航空和核工业等领域均有广泛的应用，但不锈钢和钛合金因理化性能的差异，焊接界面常形成大量脆性金属间化合物，无法得到优质的焊接结果。以扩散焊、激光焊和电子束焊为主总结了不同焊接方法的工艺参数和接头组织成分对不锈钢和钛合金焊接质量的影响，展望了不锈钢与钛合金异种金属焊接的发展趋势。

英文摘要：

Dissimilar joining between stainless steels and titanium alloys is employed extensively in the chemical, aerospace and nuclear industries, but the property of welding between them is limited by the distinction of their physical and chemical properties. The influences of parameters and compounds of different welding methods on welding quality, mainly including diffusion welding, laser welding and electron beam welding are summarized. The development trend of dissimilar joining between stainless steels and titanium alloys is forecasted.
