用射线检测技术确定焊缝缺陷深度

Radiographic Examination Technique to Determine defect depth in Welds

介绍一种将数学相似三角形原理应用于射线检测过程中,以确定焊缝缺陷深度的检测方法。通过在射线底片上的两次成像对试板中缺陷进行定位,并与实际解剖结果相比对,得到令人满意的结果。

The mathematic Similar triangle theory is used in radiographic examination to determine the depth of defects in welds. The defects in a test plate are located by imaging twice on a radiograph and the result is quite similar with that of dissecting the test plate to find out the actual position of the defect in the welds.
