摘要
分析了常规无损检测方法的特点及其局限性，讨论了以热轧无缝钢管为检测对象时检出各类缺陷的组合原则。在此基础上介绍一种由电磁分钢、涡流探伤、漏磁探伤及超声测量组成的钢管在线组合检测技术及其应用结果。实践证明。
In this paper,the characteristics and limitations of conventional NDT techniques are analyzed firstly,and the combimation principles for the NDT of hotrolled seamless steel tubes in order to detect the various defects are discussed.An online combined NDT technology is introduced,which composed of electromagnetic identification of materials,eddy current and magnetic flux leakage testing and ultrasonic measurements.It's application shows that it can supervise the steel tube production line efficiently.
