在分析焊接残余应力产生原因的基础上，对常用的焊接残余应力的测定方法和消除方法进行了分析，比较了不同方法的优缺点。在实际工作中，应根据操作难易程度、工作效率、经济成本等方面来选择合适的残余应力消除方法。最后指出研究和测定焊接残余应力对生产和科学试验具有重要意义。

Based on the analysis of the generating reasons of the welding residual stress, the common measurement and the elimination methods of the welding residual stress were researched. The advantages and disadvantages of different methods were discussed. In practical work, the appropriate methods of residual stress elimination should be chosen according to the difficulty degree of operation, work efficiency, economic cost and so on. Finally it was pointed out that the research and measurement of the welding residual stress had important significance to the manufacture and scientific tests.
