Eddy Current Flaw Detectors
Eddy current flaw detectors use electromagnetic induction to test changes in the conductivity of target materials. For example, they can identify near-surface defects and thickness inconsistencies and be used to measure distance or to detect flaws in conducting materials, including corrosion, erosion, wear, pitting, baffle cuts, wall loss, and cracks. Though similar to ultrasonic flaw detectors, they each use different technology.
