Title: ULTRASONIC FLAW-DETECTION DEVICE
Abstract:
An ultrasonic flaw-detection device provided with the following: a flaw-detection head (10) that has a probe that transmits ultrasound towards a specimen (31) comprising a composite material and receives ultrasound reflected off said specimen (31); a movement mechanism (40) that makes the flaw-detection head (10) scan the specimen (31); and a support mechanism (90) that is positioned so as to contact the bottom surface of the specimen (31) and supports said specimen (31). The support mechanism (90) is designed such that the contact area between said support mechanism (90) and the specimen (31) has a prescribed size such that the waveform of ultrasound that reflects off said contact area and is received by the probe does not exceed a certain noise level.
