Eddy Current Testing

Eddy Current is an advanced form of NDT testing that uses the electromagnetism principle for flaw detection in conductive materials. A specially designed coil energized with an alternating-current is placed in proximity to the test surface, generating a changing magnetic field that interacts with the test-part and produces eddy currents in the vicinity. Any variation in the magnetic permeability of the test-part will cause a change in the eddy current, and a corresponding change in phases and amplitude of the measured current. Changes are shown on a screen and interpreted by our team to identify defects. Our NDT team is credentialed in this highly specific technique required in aerospace component testing and other materials that may be adversely heat-impacted.
