摘要：

采用热电偶对4 mm厚6082?T6铝合金薄板双轴肩搅拌摩擦焊不同工艺焊接过程中各特征点的温度进行测定，绘制各点的热循环曲线，分析焊接过程中接头各区域温度场分布特征。研究表明：6082?T6铝合金薄板双轴肩搅拌摩擦焊时，后退侧各点的峰值温度均高于前进侧，温度差值在20 ℃左右；当热影响区温度超过250 ℃时出现β''相溶解，硬度开始呈现下降趋势；焊速不变、转速增大时，热输入量呈先增大后减小的趋势，在转速为1000 r/min时各测温点温度均达到最大值，当转速为1200 r/min时出现下降；转速不变、焊速增大时，单位热输入量降低，前进侧与后退侧的峰值温度差值由小变大，温度场250 ℃等温线分布宽度明显缩小。

Abstract:

In this paper, the thermal cycle curves of different processes of 4 mm 6082?T6 aluminum alloy bobbin?tool friction stir welding were detected using thermocouples measurement technology. Then the distribution characteristics of temperature field in the test area were analyzed. The results show that the maximum temperature of each measuring points at the retreating side of the welding is always higher than the advancing side, and the maximum temperature difference is about 20 ℃. When the HAZ temperature exceeds 250 ℃, the β'' begins to dissolve and the hardness begins to decrease. When the welding speed is constant, the heat input increases first and then decreases with the increase in the spindle speed. At 1000 r/min, the measuring point reaches the maximum temperature value, and then decreases at 1200 r/min. When the spindle speed is constant and the welding speed increases, the heat input of unit time decreases，and the difference of peak temperature increases between the advancing side and retreating side, the width of 250 ℃ isotherm is reduced considerably.
