Abstract : The patent describes an apparatus for the automatic ultrasonic checking of the quality of weld seams; it contains a two-channel flaw detector with search heads, servo system and indicating system. The proposed apparatus differs from others in that the indicator of flaws is a cathode-ray tube with persistent screen afterglow; it is supplied with two magnetic coils for deflecting the electron beam. The coils are placed on a common rotating ferrite core. The ferrite core is connected by a selsyn system to the speed checking transducer and the speed checking transducer is mechanically coupled to a drive mechanism which is used for the longitudinal movement of the tube being checked. As a result, the process of checking the quality of weld seams is simplified.
