Eddy current testers are based on the detection of variations in the electrical conductivity and magnetic permeability of a metal surface. It is commonly used in manufacturing to inspect thin metal ...

During manufacture and assembly of products, there is a wide range of testing and inspection carried out to ensure the materials and items satisfy their specifications or are fit for the required ...

Eddy currents are electrical currents induced within conductors by changing magnetic fields. They are commonly used in nondestructive evaluation (NDE) and corrosion monitoring of structures with ...

Eddy current testing has been used for at least 50 years to inspect conductive parts for surface imperfections such as cracks or scratches. Fundamentally, the technique is comparative—it only ...
