Cracks and flaws in multilayered nonferrous metal structure may be quantified by using Giant Magnetoresistive (GMR) sensor based eddy current technique. This noncontact method includes a lift-off distance as great as 3 mm. Aluminum and titanium alloy plates greater than 3 mm thick are successfully inspected. Hidden flaws in second plate down are clearly detected.
