ddy current testing

This dataset abstract presents findings from a study focused on enhancing surface crack detection in railroad safety through the development and optimization of a hybrid Eddy Current Testing (ECT) probe. Traditional ECT methods often encounter challenges related to 'lift-off noise', which arises from variations in probe-to-material distances. To mitigate this issue, the study introduces a novel probe design that integrates transmit and differential receiver coils, aimed at improving detection sensitivity and minimizing lift-off impact.
