Eddy Current Testing is a non-destructive testing method used to detect surface and near-surface flaws in conductive materials. It works by inducing electrical currents, known as eddy currents, in the material using a coil. When these currents encounter a flaw, they change in magnitude and phase, which can be measured to identify defects. This technique is commonly used in industries such as aerospace, automotive, and manufacturing to ensure the integrity of components. Eddy Current Testing is valued for its speed, sensitivity, and ability to test complex geometries without damaging the material being inspected.
