| 摘 要： | 采用搅拌摩擦焊方法对6mm厚的2A12及3A21铝合金进行焊接。对其焊接速度、旋转速度及压入量等工艺参数选择不当所产生的接头缺陷进行了分析;焊接缺陷的产生与焊接热输入及焊缝塑性金属的软化相关。当热输入不足或者塑性金属的软化程度较差时都会导致焊接缺陷的形成。

| Abstract: | 2A12Al and 3A21Al alloy in 6mm thickness was friction stir welded using the process of weld.The reasons for forming defects,welding speed,rotating speed and pressure of the shoulder, were analyzed. The results show that the defect formations is related to the heat input and deficiency material flow in the welding process. Insufficient heat input or deficiency material softening will result in the joint defect in the process. |
