摘要
用Ｘ射线法、应力释放的切块法和钻孔法对高频直缝焊管、内、外控成型螺旋埋弧焊管进行了残余应力测定。通过分析和比较指出了它们的不同物理与技术涵义。
This paper presents the results of residual stress measurement on ERW, SSAW tubes by means of X-ray, stress relaxation and hole-drilling methods. Based on the comparison of data coming from different measuring methods, the technical meanings of above three measuring methods are discussed.
