Abstract
The paper presents the results obtained from aluminum alloy 7075 T6 using eddy current testing method (ECT). This method is based on eddy current 3x3 sensor array, commanded through PC by a data acquisition system, allowing several different delay and amplitude technique at transmission and reception. The response of each sensor is stored, ensuring details for reconstructions and imaging procedures. Based on software CIVA simulation and experiment, defect characterization is obtained using the information received by each sensor of the array and establishing the position of the flaw upon the reacting sensor from array. The signal is post processed using super resolution algorithm to enhance signal to noise ratio, thus both surface and under surface flaws shall be identified, (thin or volumetric) or having different tilting reported to the surface and correlation between theoretical and experimental results.
