METHOD AND APPARATUS FOR EVALUATION OF EDDY CURRENT TESTING SIGNAL |
摘要 |
A method for evaluation of an eddy current testing signal is provided. The method includes the steps of generating a feature amount based on a sample eddy current testing signal obtained by measuring a standard specimen, the feature amount including a feature highly correlated to a secondary factor which is other than a depth of the flaw and which affects the waveform of the signal; generating an evaluation parameter by using the feature amount, the evaluation parameter being a parameter for outputting a value with a sufficiently small error relative to correct answer data on the sample eddy current testing signal; and estimating the depth of a flaw, expressed by an actual measurement eddy current testing signal, by use of the evaluation parameter.
