In this article, it introduced the working principle of digital radiography(DR) imaging technology and its application in welded pipe industry. Compared with the detection effect of traditional X-ray industrial TV from sensitivity detection, image resolution, residual magnetization, radiation dose etc. The result showed that the flat panel DR imaging technology is with some advantages, such as high sensitivity of detection, high efficiency, low labour tension, little doses of radiation and so on. It ensures the weld quality, greatly reduces the accident rate of pipeline, and can replace X-ray industrial TV detecting technology. At present, this technology is widely applied in welded pipe industry.
