| 摘 要： | 对不同搅拌头、不同工艺参数条件下的搅拌摩擦焊焊接结构宏观变形进行了测量和分析，在优化参数条件下，研究了动态控制低应力无变形焊接技术搅拌摩擦焊焊接结构宏观变形及残余应力的影响。研究表明，减小搅拌头轴肩直径、降低焊接热输入有助于减小结构宏观变形；动态控制低应力无变形焊接技术有助于减小接头残余应力，但是对结构宏观变形的作用不是很明显。

| Abstract: | Deformation of FSW stractures welded with different parameters and tools was measured and analyzed in this paper. Results showed that smaller tool shoulder and lower welding energy would reduce the deformation. With optimized welding parameters, dynamic control of welding deformation( DC-LSND) which was usually used in TIG was introduced to FSW, and its effects on structure deformation and residual stresse were also studied. |

| Keywords: | friction stir welding residual stress dynamic control low stress no distortion |
