【摘要】 焊接缺陷的实时射线成像检测是管道及压力容器制造、生产过程中的必然环节。随着数字化技术的发展,数字射线成像已成为射线检测发展的必然方向。实验研究证明用目前先进的数字平板探测器代替图像增强器可实现管道焊缝实时在线检测,同时可取代胶片照相实现对焊缝缺陷的高像质数字成像。更多还原

【Abstract】 the X ray real - time imaging testing of welding defects is inevitable segment during in the production of pressure piping and vessel. With the development of digital technology, X - ray digital imaging has become the development direction of X - ray testing. In laboratory, research proved that the advanced flat - panel detector would be used to replace image intensifier to test pipe welding on line, and replace film - screen system to obtain the high quality imaging for welding defects.更多还原
