Advanced Technology Group s.r.o. DESCRIPTION OF THE METHOD Eddy current testing method is used for testing electrically conductive materials within various fields of application. It is most commonly used for inspection of metallurgical semi-finished products, in-service inspections of tubular heat exchanger, and for aviation and automotive industry. The method belongs among so-called surface methods. Therefore it is often used for observation of surface imperfections. It is also capable of detecting imperfections in a certain depth beneath the surface (10 to 25 mm depending on material). Furthermore, the method can be applied to measu re the thickness of non-conductive coatings, or classify materials on the basis of their chemical composition or heat treatment. Its main advantages are testing rates, easy automated control and evaluation.
