摘要： An ultrasonic inspection method and ultrasonic inspection apparatus is capable of inspecting a weld line and of detecting a circumferential crack and an axial crack that are present in the weld line. An ultrasonic probe is placed on the surface of a structure and transmits an ultrasonic wave. The ultrasonic wave is transmitted at an angle in an X′-Z plane. The direction of a normal to the surface is defined as an X axis. The direction in which the weld line extends is defined as a Y axis. The direction perpendicular to the X axis and the Y axis is defined as a Z axis. An axis obtained by rotating the X axis around the Z axis is defined as an X′ axis. A control mechanism performs signal processing of signals reflected from the defect or defects to detect the defect or defects and to measure the length of the defect or defects.

摘要： Disclosed is an eddy current flaw detection probe that is capable of pressing itself against an inspection target whose curvature varies. A flaw sensor is configured by fastening a plurality of coils to a flexible substrate that faces the surface of the inspection target. A first elastic body is positioned opposite the inspection target for the flaw sensor, is obtained by stacking two or more elastic plates, and has an elastic coefficient that varies in a longitudinal direction. A second elastic body is a porous body positioned between the flexible substrate and the first elastic body. A pressure section is employed to press the first elastic body toward the inspection target.

摘要： An eddy current testing device which confirms that a change in characteristics of a target object is detected regardless of the magnitude of the change and specifying the position of a portion from which the change is detected. The device uses an eddy current probe to inspect a bent portion of a metal body, and has an inspection controller and a display unit. The inspection controller calculates a phase angle of a signal detected by the eddy current probe and generates flaw identification image data that indicates an area (or an area of the signal detected and determined to correspond to a flaw signal, based on the phase angle of the detected signal) of a flaw signal in coordinates in which the position of the portion of the target object is plotted along a coordinate axis. The display unit displays the flaw identification image data.

摘要： The present invention provides a method and apparatus for an ultrasonic inspection of a penetration of a reactor pressure vessel, especially, a welded portion of the penetration. In the ultrasonic inspection, a position (inspection position) of an ultrasonic probe relative to a portion to be inspected can be identified without an effect of the surface of a portion to be inspected.The ultrasonic probe of the ultrasonic inspection apparatus, which is pushed onto the outer surface of the reactor pressure vessel, transmits and receives an ultrasonic wave to and from a penetration having a welded portion while changing an incident angle of the ultrasonic wave. Based on a result of reception of an echo obtained by the reflection of the ultrasonic wave on the inner surface of the penetration, an inclination angle of the penetration relative to a wall surface of the reactor pressure vessel is measured. A circumferential direction position of the penetration, which corresponds to the inclination angle, is calculated based on the relationship of an inclination angle and a circumferential direction position, which have been calculated in advance. Then, the circumferential direction position can be obtained as information on the inspection position.
