Eddy Current Testing (ECT)
Eddy current testing (ECT) is an electromagnetic nondestructive testing (NDT) method which uses an alternating current passed through a coil in order to create an alternating magnetic field which intern is used to induce a localized current (eddy current) into the test object. Discontinuities such as fatigue cracks will interrupt the flow of eddy currents and alter the terminal impedance of the test coil. The amplitude and phase of the received signal can be interpreted to ascertain the severity and exact location of any discontinuities found.
Eddy current testing applications include the examination of welds, measure conductivity, grain size, hardness, and thickness; to identify materials with different composition, microstructure, magnetic permeability, and condition of heat treatment; and to determine the thickness of coatings and plating on various materials. Eddy current is routinely used to inspect a wide range of different materials and components across several fields of engineering including oil and gas, nuclear, power generation and aerospace.
