Eddy Current Inspection
Eddy current testing is an electromagnetic technique used on conductive materials to detect a number of conditions, including sub-surface defects, variations in material structure, thickness and corrosion. When an energized coil is brought near to the surface of a metal component , eddy currents are induced into the specimen. These currents create a magnetic field that tends to oppose the original magnetic field. Sub-surface defects will distort the eddy currents and alter the opposing magnetic field. By measuring how the impedance of the coil in close proximity to the specimen is affected by variations in the magnetic field, a skilled operator can precisely locate and classify sub-surface defects.
