Eddy current test detects cracks, hardness, conductivity and also checks dimensions. It is also used to sort materials. The magnitude of this test depends upon electrical conductivity of metals, size and shape of specimens,hardness of microstructure and the amount and types of defects in specimen. This test evaluates wide range of products including round and irregularly shaped objects etc.
By using this method permanent records can be maintained. It is a multi application test method. But this method requires high accuracy in calibration and the size and shape of the component is limited.
