DEVICE FOR AUTOMATED ULTRASONIC INSPECTION OF CIRCUMFERENTIAL WELDS Russian patent published in 1995 - IPC

FIELD: flaw detection. SUBSTANCE: known device do not demonstrate high reliability due to overloading of mobile part of scanner (carriage) by system feeding contact fluid and long supplying cables, due to possibility of break of these cables with movement of carriage and due to irregularity of feed of contact fluid into seeking heads. Proposed device is provided for increase of reliability with suspension including clamps (magnetic, for instance) for its attachment on article in inspection zone carrying vessel with contact fluid, pump to feed fluid into seeking, input and output intermediate connectors electrically interconnected, elements for hand control of carriage. Suspension is coupled to remote equipment by means of main bundle of cables through input connectors and to carriage through output connectors with the aid of intermediate bundle which length is somewhat longer than length of circumference of article and to seeking heads by elastic tube to feed contact fluid from pump. Vessel with contact fluid is mounted on Cardan fork providing its vertical position in any spatial position of suspension. EFFECT: high reliability of device. 2 cl, 3 dwg
