摘要
从钢管常用的检测方法出发 ,叙述了电磁超声检测的原理、钢管缺陷的电磁超声检测模型及钢管缺陷的电磁超声检测的研究方向 ,特别提出以铁磁材料为检测对象的磁场的计算尤为重要和迫切。
From the traditional inspection and measurement method of steel tube, the paper stated the principle of electric magnetic ultrasonic inspection and measurement, the electric magnetic ultrasonic inspection and measurement mode of steel tube defects and the research direction of the electric magnetic ultrasonic inspection and measurement of steel tube defects. The paper specially proposed that the calculation of magnetic field for the inspection and measurement with iron magnetic material would be more important and urgent.
