建立内检测与射线底片中制管焊缝与环焊缝相交位置长度识别模型，利用自动识

; Detecting the radiation backsheet pipe girth weld and the intersection length recognition model, by an automatic identification system for identifying and matching, it is determined by comparing the consistency of the weld and the backsheet radiation and issue a report to establish <br>the charge of the scan The results of the comparison of the digital radiographic film and the consistency of the welding port and the film are recorded in the PIS database.

The identification model of the position length of the internal detection and ray film tube weld intersecting the ring weld is established, the identification and matching is made by using the automatic recognition system, and the consistency between the weld and the ray negative is determined by comparison and the report is issued;<br>Responsible for the scanned digital ray negatives and welds and negativeconsistency ratio simply entered into the PIS database.

The length identification model of intersection position between pipe weld and girth weld in internal inspection and radiographic film is established. The automatic identification system is used to identify and match. The consistency between weld joint and radiographic film is determined by comparison and a report is issued;<br>Be responsible for inputting the scanned digital radiographs and the consistency comparison results between welded joints and negative films into PIs database.<br>
