摘要
Bio-Imaging Research, Inc. (BIR) has recently developed and fielded an automated digital radiographic (DR) weld inspection system called RLS (Radiographic Line Scanner). RLS is being used for integrity verification of 16 mm ( inch) thick plasma arc steel butt welds to a radiographic inspection quality of 2%-1T. The system inspects these welds with a throughput of 30 mm (1.2 inches) of weld length per minute, and provides real time, scrolling display of the image during inspection. The present RLS mechanical configuration moves the weld past a stationary radiation source and detectors; a configuration moving the source and detectors past a stationary weld is also possible, with the same imaging quality.
