    摘要: A magnetic testing method and apparatus can accurately detect a flaw by magnetizing a test object to such a degree that the object becomes magnetically saturated while solving the problems of a large magnetizing device is required when only a DC magnetic field is applied and that the test object generates heat when only an AC magnetic field is applied.A magnetic testing apparatus comprises a first magnetizing device for applying a DC bias magnetic field to a test object P in substantially parallel to the direction in which a flaw F to be detected extends, a second magnetizing device for applying an AC magnetic field to the test object P substantially perpendicularly to the direction in which the flaw F to be detected extends, and a detecting device for detecting leakage flux produced by the magnetization of the test object P accomplished by the first and second magnetizing devices.

    摘要: A rotary eddy current flaw detection probe device has a plurality of Θ-shaped eddy current flaw detection probes attached in a rotating disc for detecting flaws in all directions regardless of the flaw direction. Four Θ-shaped eddy current testing probes P11 to P22 are arranged around the rotation center Ds1 of a rotating disc 111 and are embedded in the disc 111. The coil planes of detector coils Ds11 to Ds22 of the testing probes P11 to P22 are parallel with each other, and are perpendicular to the rotation plane of the rotating disc 111. The coil planes of the detector coils incline at an angle θ relative to a line Y passing through the centers Ps11 and Ps12 of the probes P11 and P12. The detector coils Dc11 and Dc12 are cumulatively connected to each other and the detector coils Dc21 and Dc22 are differentially connected to each other.

    摘要: In an eddy current testing method which involves using a rotatable eddy current testing probe in which a detection coil is arranged within an exciting coil, a change in detection sensitivity (a deviation of detection sensitivity) which changes depending on the rotational position of the detection coil is reduced. The eddy current testing probe includes an exciting coil EC1, a detection coil DC1, an exciting coil EC2 and a detection coil DC2, which are mounted on a disk DS. The eddy current testing probe is placed so as to face a circumferential surface of an object to be inspected T, which is in the shape of a circular cylinder, and the disk DS is rotated. Then, the distance (liftoff) between the detection coils DC1 and DC2 and an inspection surface changes. Therefore, also the detection sensitivity to a flaw signal changes. To reduce the change in detection sensitivity, the detection sensitivity is adjusted by detecting the rotational position (rotational angle) of the detection coils DC1 and DC2.

    摘要: An apparatus 1 for determining a kind of a steel material detects a spark pixel from a color picked-up image 2 of a spark 19 produced when a steel material 18 is ground, and detects a pixel, in which the density of any one color component for judgment selected from among RGB color components is low, as a low-density pixel from the spark pixels. The apparatus 1 determines that the steel material is a steel material consisting of the high-strength steel if the ratio of the total number of low-density pixels to the total number of spark pixels is not lower than a threshold value for judgment, and determines that the steel material is a steel material consisting of the ordinary steel if the ratio is lower than the threshold value for judgment.
