Abstract

PURPOSE: To improve an inspection accuracy and reduce an inspection time by focusing ultrasonic beams in linearity by providing a circular wedge having a hole equal to that of the annular ultrasonic vibrator, and a specified angle of inclination.
CONSTITUTION: A circular plastic wedge 2 having a hole equal to that of an ultrasonic vibrator 1 at the center and a specified inclination 7 on the inner side is provided closely adjoining the vibrator 1. A cylindrical sound absorbing member 3 is provided at the hole part. When detecting defects immersedly with an ultrasonic transmitter/receiver thus formed, an angle 7 of inclination of the wedge 2 is so set that the reflected wave from the water surface is absorbed by the sound absorbing member 3. Thereby, the ultrasonic beam from the vibrator 1 is focused in linearity and makes incidence onto the test material. Accordingly, a detected flaw position can be located at a high accuracy along with a less inspection time.
