【Abstract】 The bobbin tool friction stir welding technology improves the problem of not being able to weld hollow and complex parts during the traditional friction stir welding process. It is a new type of friction stir welding technology. However, it is still in the initial stage of development, and relevant theoretical and applied research is relatively rare. In this paper, the research status of the tool’s structure, weld formation, joint microstructure and mechanical properties, temperature field research and application prospects are introduced, which provides reference for future development and engineering application.更多还原
