摘　　要：为解决摩擦叠焊单元成形过程中塞棒与孔侧壁结合强度不足的问题,研究了塞棒形式对摩擦叠焊单元成形质量的影响。采用8种不同形式的塞棒分别进行焊接试验并对接头进行拉伸试验。通过对接头的宏观照片及拉伸试验结果进行对比,分析不同塞棒形式对叠焊单元焊接质量的影响。结果表明,通过对塞棒形式的不断优化,可以减少焊接缺陷,提高焊接质量。To solw problem of insufficient strength between the rod and sidewall on the friction Hydro Pillar Proeessing, influence of rod form on the quality of Friction Hydro Pillar Processing has been studied in this paper. The experiments were done for eight forms of rod and the tensile tests were done for wehting joints. By comparing the microphotograph of joints and results of tensile tests, influence of rod form on the quality of Friction Hydro Pillar Processing was analyzed. The results show that welding defects can be reduced obviously and the quality of welding can be impruved by optimizing the form of rod.
