ULTRASONIC INSPECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an ultrasonic inspection device capable of precisely and easily performing inspection for internal defect, void or peel-off on an inspection object the interior of which is two-dimensionally displayed.SOLUTION: The ultrasonic inspection device includes: an ultrasonic transducer 2 that irradiates an ultrasonic to an inspection object 3 to obtain an echo signal; a region definition section 16 that defines a marked area R in the inspection object 3; a rotation mechanism that rotates either one of the inspection object 3 and the ultrasonic transducer 2; and a two-dimensional imaging section 21 that creates an image of a plane in which a defect image area is the maximum in the arbitrary cross-sections perpendicular to a set axis of an image of a defect 4 which is recognized by the echo signal from the marked area R.
