Аннотация
Current radiography-based acceptance criteria do not always guarantee consistency in opinion among experts who are involved in interpretation of radiographs. To improve this consistency, which to a large extent determines the objectivity of the technique, the authors propose classification of radiographic images by shape and appearance in order to simplify weld-defect identification. The acceptance criteria of the RD-25.160.10 KTN-016-15 regulatory document for weld joints in Category 2 oil trunk lines are referred to as an example. The criteria that were developed on the basis of the image classification were used in a statistical experiment that involved six experts. The experiment showed that the number of cases of a substantial degree of consistency of the expert opinions increased by 2.2 times compared to the criteria that are currently in use.
