eddy current inspection
Eddy current inspection is anon-destructive testing method that uses electromagnetic induction to find flaws like cracks and corrosion in conductive materials It involves passing an alternating current through a coil to create a magnetic field, which induces eddy currents in the conductive material being tested. Flaws in the material disrupt the flow of these eddy currents, and the changes in the coil’s impedance are measured to detect and locate imperfections. This technique can also measure material and coating thickness, material identification, and heat treatment monitoring
