CONTRIBUTION TO THE LOCALIZATION ALGORITHM USING WAVELETS IN THE MULTIFREQUENCY DEFECTOSCOPY BY EDDY-CURRENTS

Ján Grman

   Fast localization of defects and structure elements in the defectoscopy of steam generator tubes is the field where application of wavelet transformation is very perspective. Primary task is to find positions of potential indications within signal and secondary task is to calculate optimal boundaries of indications with respect to their future use in process of classification. Paper presents modifications to already presented localization algorithm based on method of wavelet transformation.

Keywords: defectoscopy, localization, eddy-currents, multifrequency
