| 摘 要： | 为了评价无缝钢管表面缺陷的严重程度，必须估测出缺陷的深度、宽度等参数。文章阐述了漏磁探伤中缺陷参数和漏磁信号的相互关系。通过对实验结果的分析表明：缺陷的深度、宽度及倾角分别与漏磁信号的幅值成一定的函数关系，根据信号的特征可反演出缺陷的大小。

| Abstract: | In order to assess the seriousness of a defect in the surface of the seamless steel pipe,its depth and width must be estimated.The relation between defect parameters and magnetic leakage signal is discussed in this paper.The result analysis shows that there are certain functions between the depth,the width,the inclination of defect and magnetic leakage signal.The size of defect can also be determined by the signal features. |
