Background In the production process of spiral seam submerged arc welded pipe, the radiographic inspection is taken as a key quality control measure, and plays a vital role in ensuring the safety and reliability of the pipeline. The radiographic inspection technology evaluates the quality of a steel pipe by detecting whether defects such as cracks, pores, slag inclusions, etc. exist inside the steel pipe by penetrating the steel pipe using X-rays or gamma rays. The technology can accurately reveal the slight change of the internal structure of the steel pipe based on the absorption difference of rays passing through different materials. However, in practice, the radiographic inspection process faces some technical challenges, especially in the selection of the path of the steel pipe. Currently, most radiographic inspection systems set inspection paths manually or semi-automatically, which means that technicians need to manually plan the moving path between the radiographic source and the steel pipe according to the specific specifications of the steel pipe.
