Eddy Current Inspection
| In liquid penetrant nondestructive testing, dye flows into a sample's cracks and defects and makes them visible, either to the naked eye or under fluorescent light. In much the same way, Stork Materials Technology scientists employing Eddy Current inspection direct electrical currents to flow over a sample.
Eddy Current is an efficient and precise method; this type of inspection is particularly helpful for heat exchangers and aircraft parts and components. A flow of periodic electrical currents in conductors called probes creates varying electromagnetic fields. These probes are placed in close proximity to the surfaces of the test materials, and can detect effects of processing and shaping operations during production, as well as corrosion damage or cracking for most nonmagnetic metals and alloys.
