PURPOSE:To allow high speed, high resolution ultrasonic flaw detecting operation for a specimen having free curve surface through a simple mechanism. CONSTITUTION:The ultrasonic flaw detecting system wherein an untrasonic probe 1 movable in Z-direction and communicating ultrasonic wave with a specimen scans, through a scanning means 4, on the specimen in the direction perpendicular to Z-direction to obtain ultrasonic signals from the specimen comprises means 19-21 for supporting the scanning means 4 movably in Z- direction with respect to the specimen, a dummy specimen 33 having surface profile simulating that of the specimen, and a copying means 22 moving up and down in Z-direction while copying the surface profile of the dummy specimen 33 thus moving the scanning means 4 in Z-direction. |
