Abstract

A weld inspection process and an associated system for the determination and assessment of weld seams by first producing a flawless weld seam on a test specimen, making a point by point inspection of the test specimen using a pair of alternately pulsed X-ray or gamma ray sources, while generating signals which may be simultaneously displayed and stored, to form a permanent record of the test specimen weld seam, on a target plate. A point by point comparison of is made of a new, similar weld and the recorded image is instantaneously compared with the previously recorded, stored image of the flawless test weld. In the event of identical images, that point of the weld is deemed flawless, while a lack of identity indicates a flaw, in which event, the defective position is marked for subsequent repair, removal or total rejection.
