摘要：
Since the integrity and mechanical properties of welded joints mainly depend on the solidification behavior of the weld pool and the microstructure characteristics of the welding heat affected zone, it is crucial for engineers and scientists to reveal the solidification behavior of the weld pool and the structural transformation of the welding heat-affected zone. With the dramatical improve of material calculation methods, the formation mechanism of the microstructure of some metal welded joints has been continuously revealed. In this article, the application of computer simulation in the study of welded joint microstructure is comprehensively analyzed. It focuses on the difficulties of simulating each area of welded joints, the advanced simulation methods applicable to each area and the current research status. Based on the characteristics of welded joint formation and simulation methods, some hot issues in research are proposed, aiming to provide effective help for researchers in related fields and open up new research ideas.
