Abstract:

Periodically, manufacturers of large caliber projectiles have lost valuable time due to failure during calibration checkout of ultrasonic inspection systems, after which the bonded production was to be recalled for reinspection. The method for verification of ultrasonic inspection provides a means for verification during andor after inspection of each part. Implementation of such methods yields immediate release of inspected parts for further processing. Ultrasonic inspection systems that are presently operating have limited FAIL SAFE functions. The fail safe features in the present systems are related more to mechanical functions and operations than to the most critical part, the ultrasonic flaw detection loop which includes the electronic system and the transducers. The only part of that system that is presently monitored is the pulserreceiver and only for as far as its operation is concerned. The effort addressed in this report concerns use of reflectors and electronic monitoring to assure proper system calibration during each inspection cycle.
