摘要
系统地总结和分析了国外搅拌摩擦焊用搅拌头的研究发展现状 ,并指出了每种搅拌头的设计思想、作用和优缺点。通过各种搅拌头的比较 ,指出了可自动变轴肩尺寸且可自动伸缩式搅拌头是最有发展前景的搅拌头技术 ,该技术解决了搅拌摩擦焊接技术早期应用中所遇到的一系列难题。同时指出了如何获得耐高温、高强度的搅拌头仍然是目前搅拌摩擦焊领域急需解决的难点。
This paper summarizes the research status of rotational tool used for friction stir welding, and analyzes the designed principle, advantages and disadvantages of each kind of tool. Through the comparison among tools, it is pointed that auto-adjustable tool can conquer keyhole problem and be used in variable thickness material welding. At the same time, this paper points out that how to obtain high-strength, high temperature resistance tool remains the key for friction stir welding development.
