Abstract：The research status of formation mechanism and control measures of intermetallic compounds in laser welding joints of Al/steel, Ti/steel, Mg/Al and NiTi SMA/SS are reviewed. The effects of different base metal compositions and different welding processes on intermetallic compounds in welded joints are compared and analyzed. Effective control of intermetallic compounds can be achieved by adding intermediate fillers, controlling heat input, and adopting hybrid welding processes, thereby optimizing welded joint structure and improving mechanical properties. The research progress of material computing in simulating and predicting the structure and performance of intermetallic compounds in laser welding joints of dissimilar metals is also reviewed.
