Abstract : A review is made of the pulse-echo method of ultrasonic imaging as a technique in nondestructive evaluation. A discussion on the image formation of A-, B-, C-scans and three-dimensional display is included. Scanning patterns obtained from a testing block are shown. Finally, the method is evaluated for finding interface voids of metal-composite compound cylinders. Preliminary experiments were made and the results are given. A special probe with multiple transducer is suggested.
