Abstract

The paper proposes a new probe for enhancing crack evaluation in eddy-current non-destructive testing. The probe consists of one exciting coil and two identical pick-up coils. The pick-up coils are situated at different locations relative to the position of the exciting coil for gaining signals using various depth profiles of eddy current density. The two signals are linearly superposed and a certain indication of crack's depth is extracted from the resulting signal. Numerical as well as experimental results demonstrate the effectiveness of the new probe in the evaluation of a crack's depth. In addition, cracks much deeper than the standard depth of penetration can be evaluated using the new probe.
