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： The surface length of a metal subject to be inspected is evaluated by detecting an eddy current without using a combination of a scale and visual or liquid penetrant inspection. An exciting coil and a detecting coil are scanned above the subject in a length direction. An eddy current detector measures an output voltage corresponding to scanning positions based on an output from the detecting coil. Based on an output voltage distribution curve indicating a distribution of output voltages corresponding to the scanning positions, position information is extracted corresponding to values which are within a differential voltage range and lower by 12 dB than a maximum value of the output voltages on the left and right sides of the distribution. A distance between the positions included in the extracted information is calculated to evaluate the length of a slit which is a defect present on the subject surface.

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.
