AN APPARATUS FOR AUTOMATIC ULTRASONIC CHECKING ON THE QUALITY OF WELD SEAMS (Ustroistvo dlya Avtomoaticheskogo Ultrazvukovago Kontrolya Kachestva Svarnukh Shvov),
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.
