Understanding Eddy Current Testing ET Module 18

Eddy Current Testing (ET) is a nondestructive testing (NDT/NDE) method that uses electromagnetic induction to detect surface and near-surface discontinuities in conductive materials. In this module, we cover the basic principles of eddy current testing, how eddy currents are produced, factors that affect test signals, probe types, common applications, and the advantages and limitations of the process. This lesson is designed for students, inspectors, welders, QA/QC personnel, and anyone interested in nondestructive examination methods used in industry.
