薄壁圆环激光焊缝X射线实时成像检测应用

Radioscopy Applying to Thin-wall Laser Jointing Rings

摘要: 利用射线照相的替代技术——X射线实时成像检测技术，对某薄壁圆环的焊缝进行了实时成像检测，结果表明该技术可以检测出试环焊缝中最小为0.4 mm的孔型缺陷，像质计测定的检测灵敏度优于2%。

Abstract: As a new technology substitution of film radiography, radioscopy is used to test the welding of jointing ring. The result shows that the hole style defect with  0.4 mm can be detected and its image quality indicator sensitivity is lower than 2%.
