Title:
ULTRASONIC INSPECTION METHOD AND DEVICE
Document Type and Number:
Japanese Patent JP2014163805
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an ultrasonic inspection method and device that, in inspecting an inspection object having a complicated shape part such as a rotor blade implanting part of a turbine rotor, clarify a correspondence between the shape of the inspection object and an echo on a flaw detection image and facilitate identification of a defective echo appearing at a defect-assumed position without requiring a highly precise probe scanning tool or position detection means.SOLUTION: An ultrasonic inspection method for detecting a defect generated in an inspection object while electronically scanning an ultrasonic beam with an array type probe, comprises: associating a reflection source position on a shape diagram of the inspection object with a shape echo on a flaw detection image; generating a corrected flaw detection image in which correction is performed to the flaw detection image so that the display position of the shape echo matches the reflection source position on the basis of a positional relation between the reflection source position and the shape echo; and displaying the corrected flaw detection image in such a manner as to superimpose the corrected flaw detection image on the shape diagram.
