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