| description | Equipment of the invention provides ultrasonic flaw detection equipment using a volume focusing flaw detection method, the ultrasonic flaw detection equipment described below. That is, this equipment performs internal flaw detection of a material being tested, the material having a virtually circular cross-sectional shape, and transducers 1 . . . 1 are arranged in an arc along a circle exhibited by the material being tested. Array probes 10 . . . 10 are disposed so as to surround the material being tested. An exciting unit enables flaw detection of the material being tested to be performed by vertical and oblique flaw detection methods. The exciting unit makes ultrasonic waves enter the material being tested from each position on an incident section as a result of a plurality of transducers being vibrated once and makes the ultrasonic waves reach a counter section facing the incident section on the circumference of the circle exhibited by the material being tested, and the exciting unit makes the ultrasonic waves enter the material being tested as a result of the plurality of transducers being vibrated one more time and makes the ultrasonic waves allowed to enter reach one of adjacent sections adjacent to the counter section. |
