testing capabilities Eddy Current Testing (ET) Eddy Current Testing (ET) is a non-destructive testing (NDT) method that uses electromagnetic induction to detect surface and near-surface flaws in conductive materials. When an alternating current flows through a coil, it creates a magnetic field that induces circulating currents (eddy currents) in the test material. Disruptions to these currents caused by cracks, corrosion, or changes in material properties are measured and displayed, revealing potential defects. How the Test is Performed Preparation – The fastener or component is cleaned to remove dirt, grease, or coatings that might affect results. Coil Excitation – A probe containing a coil is energized with alternating current, generating a magnetic field. Induction of Eddy Currents – As the probe is placed near the conductive material, eddy currents are induced within the component. Disruption Detection – Any discontinuities, such as cracks or changes in material thickness, disrupt the flow of eddy currents. Signal Analysis – Variations in the currents are detected by the probe and displayed for interpretation by skilled inspectors. Documentation – Results are recorded to verify compliance and provide traceability. Why It is Performed Eddy Current Testing is performed because it is fast, highly sensitive, and effective for detecting surface cracks, corrosion, and material variations without damaging the part. Unlike some other methods, ET requires minimal surface preparation and can often be performed quickly on complex shapes, making it well-suited for fasteners and precision components.
