EDDY CURRENT FLAW DETECTION DEVICE, EDDY CURRENT FLAW DETECTION METHOD, AND EDDY CURRENT FLAW DETECTION PROGRAM |
摘要 |
There is provided an eddy current flaw detection technique capable of, even when inspecting an object having a narrow portion with a small curvature radius, recognizing detection sensitivity change due to change of attitude of a probe. An eddy current flaw detection apparatus 10 includes: an AC power source 14 which generates an excitation magnetic field in each of excitation coils 12a accommodated in a probe 11 to excite an eddy current in an inspection object 13; a detecting section 15 which detects a detection signal generated by an induction magnetic field induced by the eddy current in each of detection coils 12 accommodated in the probe 11; an output section 16 which outputs flaw detection data based on the detection signals; a storage section 17 which mutually associates and stores the detection signals detected at the same timing from the plurality of coils 12b; and an evaluating section 18 which evaluates an attitude of the probe 11 based on the plurality of detection signals detected at the same timing and associated with each other. |
