Ultrasonic flaw detector and ultrasonic flaw detection method for objects having a complex surface shape |
摘要 |
An ultrasonic flaw detector including an ultrasonic probe for emitting an ultrasonic wave on an object to be inspected and receiving a reflected ultrasonic wave from the object, a drive element control unit for controlling a plurality of ultrasonic elements to emit an ultrasonic wave on the ultrasonic probe and to control a reflected ultrasonic wave from the ultrasonic probe, and a calculation unit for obtaining, by using a refraction angle of the ultrasonic wave at a time of the ultrasonic wave entering the object, an incident position of the ultrasonic wave on a surface of the object, and a surface shape of a surface of the object at the incident position, the incident angle of the ultrasonic wave entering the incident position, and obtaining a plurality of ultrasonic elements to be driven, based on the incident position and the incident angle. |
