简要介绍钢轨焊缝中的缺陷及其探测方法 ,重点研究双探头探伤时平面状缺陷反射幅度与缺陷位置的关系和单探头探测轨脚时声波的传播规律及探头偏角的选择等。
Briefly introduce the defects in the weld of the rail and the detection methods. The emphasis is on the relationship between the reflection amplitude of the planar defect and the position of the defect when detecting the double probe.
