Advanced / Specialist Non-Destructive Testing

Eddy Current TestingĀ  (ECT)

An electromagnetic induction technique detecting surface breaking and near-surface defects, the sorting of materials and grades, the measurement of the thickness of non-magnetic materials, the measurement of the thickness of the covering, etc in all electrically conducting Materials through paint and surface coatings. All electrical Methods are indirect; a material property is measured as An electrical property variation. The detection of near-surface defects, the eddy current penetration depth, and therefore the testing depth, directly depends on the electrical and magnetic properties of the material to be tested (from a few hundred microns for steel to several millimeters for aluminum) as well as on the probe frequency used.

Eddy current inspection is the accepted method for The inspection of non-ferromagnetic tubing in the vast majority of cases.
