  • Publication number: 20220299451
    Abstract: In a nondestructive inspection of a defect of a welded portion of a pipe or a pipe member, work efficiency of a radiation transmission test is improved by reducing a burden on a worker, and an inspection accuracy is improved. Imaging data is acquired by transmitting radiation through a welded portion of the pipe to be inspected. Processing of associating determination data indicating a result of determining a defect of the welded portion of the pipe to be inspected based on a distribution of a transmission intensity of the radiation obtained from the imaging data with image data showing the distribution of the transmission intensity of the radiation is performed. As a result, through use of the imaging data, image data and determination data associated with the image data can be obtained, and the burden on the worker can be reduced.
