✦ Synopsis

A phased array ultrasonic testing method is expected to be applicable to nuclear power plants for electrical ultrasonic beam control and real time B-scope image display. The availability of the phased array ultrasonic technique has been investigated and it has been verified that the sound beam is electrically steered to the intended angle and is electrically focused at the intended position. From the results of experiments, the dynamic aperture sizing technique was established as a practical method and this technique was demonstrated for artificial flaws.
