Keywords:Eddy , Multi coil probe, Defect identification, Phase angle

Eddy current testing (ECT) with multi coil probe has been developing for enhancing surface inspection. Defect extraction method based on phase angle of lissajous waveform was effective to identify between defects and noises.
This paper describes applicability of crack extraction method.
