DIGITAL RADIOGRAPHIC WELD INSPECTION SYSTEM

摘要

Disclosed is a weld inspection system that utilizes an automated digital radiographic camera (110) and control system (126) to generate and review digital X-ray images of the weld system. The weld inspection system is mountable onto the weld fixture (100), such that the weld inspection system can inspect welds (200) upon completion of welding operations while the barrel panels (102) are still clamped in the weld fixture (100). The digital radiographic camera (110) includes a fiber optic scintillator X-ray to light conversion screen coupled to a high resolution charged coupled device (CCD) camera (110) to produce digital radiographic images of a portion of the weld (200) between welded barrel panels (102). An X-ray source (116) is located in a shielded housing which is attached to a carriage that is movably mounted to the vertical weld fixture (100) on the concave side of the barrel weld. The digital radiographic camera (110) is attached to a carriage that is movably mounted to the vertical weld fixture (100) on the concave side of the barrel weld (200).
