Abstract: Dissimilar material structures could realize the combination of dissimilar materials with excellent performance, which improves the flexibility in design and production and meets the demand for function and properties in modern engineering structures. These structures have been widely used in many fields due to their higher technological and economic value. Therefore, reliable joining of dissimilar materials is becoming increasingly important. Nevertheless, the great difference in physical and chemical properties between dissimilar materials poses a huge challenge to achieve reliable joining. This work reviewed the research status and development on brazing, laser welding, electron beam welding, arc welding, and friction stir welding of dissimilar materials in China and abroad. Based on this, summaries and prospects about dissimilar joining are given, which provides a reference for research interests and technology breakthrough in the future study.

Key words: dissimilar materials, brazing, laser welding, electron beam welding, arc welding, friction stir welding
