Electromagnetic Testing For Metal Parts by Eddy Current Machine - Magkraftndt

Electromagnetic Testing, using Eddy Current Testing , is a non-destructive testing technique used for testing metal parts for cracks, failures, or changes in material condition without causing any damage whatsoever. It operates on the principle of electromagnetic induction. The eddy current testing creates a magnetic field when an alternating current flows through a coil. When this coil is held near a conducting metal surface, eddy currents are induced in the material. In the case of defects such as surface cracks, corrosion, or thickness changes, disruptions occur in the eddy current flow. These changes are detected and evaluated for flaw classification. The rapidly evolving eddy current testing industry is characterized by industries like aerospace, automotive, and general manufacturing. It is one of the quickest and most accurate methods available, and, generally speaking, it does not make contact with the test surface.The eddy current testing machine is ideal for inspecting aluminum, copper, and steel components. In summary, eddy current testing is a screening method of proven reliability and efficiency for metal testing.
