摘　　要：通过拉力载荷消除残余应力实验,求得了用拉力载荷消除焊接残余应力的充要条件和导出了焊接残余应力消除量计算式;并发现了惯性反弹现象,指出了残余应力的消除,须经一个由不稳定期到稳定期的过程。The paper presented the essential and sufficiend conditions to relieve of weld residual stress by tensile load method, the equation to calculate the relieved amound of weld residual stress was deduced, and the phenomenon of inertial leap was observed, experiments showed that the stress relieving process was unstable at the very beginning and then stable hereafter.
