To provide an ultrasonic flaw detection device and method, capable of facilitating the display positional alignment of three-dimensional flaw detection data with three-dimensional shape data, thereby quickly identifying a flaw echo and a shape echo.
A computer 102A generates three-dimensional flaw detection data from the waveform recorded in a data recording part 102E. A three-dimensional display unit 103 displays the three-dimensional shape data of an inspection target and the three-dimensional flaw detection data generated by the computer. The computer 102A corrects the relative display position of the three-dimensional shape data and the three-dimensional flaw detection data on the basis of a coordinates system defined by the surface and point constituting the three-dimensional shape data displayed on the three-dimensional display unit to display the three-dimensional shape data and the three-dimensional flaw detection data by superposition.
