X-ray inspection of welds

摘要: X-ray equipment for nondestructive testing and particularly mechanized of the integrity welds along length includes means mechanically traversing an source one side weld a grainless fluorescent screen other side, with coupled to image-isocon video camera, preferably through light intensifier. The display shadow picture from camera super-imposing identifying indicia, recording composite indicia picture. image is integrated over at least several frames so as minimize "noise" intensify contrast. In addition, signal ultrasonic transducer may be provided indicate operator existence probable flaw in metal.
