ABSTRACT:
A method, apparatus and system for the ultrasonic detection and evaluation of flaws in annular test objects including an arrangement of ultrasonic transducers that are rotated about the outer surface of the test object and provide an ultrasonic indication fo flaws in the object, and for electronically collecting, storing, and analyzing the flaw data gathered by the ultrasonic transducers, to further provide a predetermined objective indicia of acceptablility concerning the structural integrity of the test object.
