Patent attributes
An ultrasonic flaw detection device includes: an ultrasonic probe that detects waveform data of ultrasonic echoes emitted to an inspection area of an inspection target; a processing unit that stores pieces of sampling data obtained by sampling the waveform data obtained by the ultrasonic probe at predetermined sampling intervals in a storage unit continuously in time series; and a display control unit that divides the inspection area into a plurality of divided areas and displays each of the plurality of divided areas on a display, wherein the processing unit directly or indirectly links a divided area of the plurality of divided areas to one or more waveform data containing sampling data of one or more sampling point included in the divided area.
