Eddy Current Array (ECA) is an advanced non-destructive testing (NDT) technique used for the rapid and reliable detection of surface and near-surface defects in conductive materials. By utilizing multiple eddy current coils arranged in an array, this method enables wide-area coverage with high resolution, significantly improving inspection speed and accuracy compared to conventional eddy current testing.
