摘要
二次应力的合理处理是影响含缺陷焊接结构完整性评定时的难点问题。二次应力修正因子的可靠性直接影响评定结果的可靠性。本文结合具体工程实例对三种典型的二次应力修正因子的可靠性进行了分析 ,得到了几点具有参考价值的结论。
The reasonable handling of secondary stress modified factor is defficult point problem,affect the integrality of welding structure with defects,in evaluation.The reliability of secondry stress modified factor affects directly the reliability of evaluation result.In this article in combination with specific engineering example,the reliabilities of three typical secondary stree modified factors are analyzed.Some conclusins with reference value are obtained.
