| 摘 要： | 研究了等径弯曲通道变形AZ31镁合金的搅拌摩擦焊工艺,对焊缝的成形特点和力学性能进行了分析.试验结果表明,对厚为15mm的等径弯曲通道变形AZ31镁合金板,工艺参数对焊缝成型有很大的影响,成型性能对焊接速度的敏感程度较铝合金板要大,当焊接速度为37.5mm/min和搅拌头旋转速度为750r/min时,可以获得较好的焊接质量.

| Abstract: | An investigation was carried out on the FSW of AZ31 magnesium alloy processed by equal channel angular pressing with a thickness of 15mm.The basic characterization of the weld formation and the mechanical properties of the joints were discussed.The result shows that the effect of welding parameters on welding quality was evidence and welding quality is sensitive of traveling speed.Sound joint can be obtained when welding speed is 37.5mm/min and rotating rate of welding pin is 750r/min. |
