What Does Eddy Current Testing (ECT) Mean?
Eddy current testing is an electromagnetic evaluation method that uses electromagnetic induction to find and characterize surface and subsurface defects in conductive materials.
A specific type of eddy current testing is pulsed eddy current testing (PEC).
Corrosionpedia Explains Eddy Current Testing (ECT)
The eddy current testing method is used to detect cracks in metal sheets in the aerospace industry and in other manufacturing and service environments where a through and proper inspection of thin metals is required for safety or quality-related problems.
