摘要： 利用测力传感器对6082-T6铝合金回填式搅拌摩擦点焊过程中的Z向负载进行了测量，研究了搅拌摩擦点焊过程中不同焊接工艺参数(轴肩转速、搅拌针转速、扎入/回抽时间和扎入深度等)对负载的影响.结果表明，铝合金搅拌摩擦点焊试验中负载曲线可分为压紧环下压区、轴肩扎入区、搅拌针回填区和搅拌头卸载区四个部分.试验负载随轴肩(或搅拌针)转速的增大出现波动下降的趋势；焊接负载随轴肩扎入/回抽时间的增加而逐渐降低；焊接负载也随轴肩扎入深度的变化而变化，但没有发现特定影响规律.

关键词: 回填式搅拌摩擦点焊, 铝合金, 转速, 负载, 扎入深度

Abstract: The Zaxis loads were measured in the process of 6082T6 aluminum alloy refill friction stir spot welding and the influence of different welding parameters(shaft shoulder rotate speed， stirring pin rotate speed， tying into/withdrawing time and tying into depth， etc.)on loads was studied. The results show that curve of loads in the process of aluminum alloy refill friction stir spot welding can be divided into 4 zones: clamp ring pushing process， shaft shoulder tying into process， stirring pin refill process and stirring tool unloading process. Loads in the test reduce fluctuation as the rotating speed of shaft shoulder or stirring pin increases. Loads in the test reduce gradually as the shoulder tying into/withdrawing time increases. Loads in the test fluctuate without showing a trend as the shoulder tying into depth increases.

Key words: refill friction stir spot welding, aluminum alloy, rotate speed, load, tying into depth
