中文摘要：通过正交试验得出活塞杆连续驱动摩擦焊接工艺参数中对接头抗拉强度的影响顺序是顶锻保压时间，顶锻压力，主摩擦压力，主摩擦时间。为在生产实际中制定焊接工艺规范提供了重要的参考依据；利用极差法得出了优水平组合，并通过实验进行了验证，实验结果与正交试验计算结果基本一致。
英文摘要：By orthognal experiment,the sequence of techonlogical paraments of continious drive friction welding effecting the strength of the the welded joint of piston rod is upset pressure time, upset pressure, main friction pressure and main friction time.These provide important reference for establishing technological parameters of friction welding in practice.By range method, reached the superior level of combination and compared with the experiment, The field obtained from experiments was consistent with that of the calcu
