Eddy Current Testing Equipment FAQs
How does eddy current measurement work?
Eddy current testing is a nondestructive testing (NDT) method that can be used for various inspection and detection applications. Eddy current inspections work using an electromagnetic field to measure the response from a material. Eddy current testing equipment generates magnetic fields, which induce a current that flows in a test piece (e.g., a conductor such as a coil). This influences the magnetic field, as well as the magnitude and phase of voltage in the coil. Any changes in conductivity, such as defects or thickness differences, can affect the resulting eddy current. This technology can then be used to measure distance or to detect flaws in conducting materials such as corrosion, erosion, wear, pitting, baffle cuts, wall loss, and cracks.
What is eddy current testing equipment used for?
Eddy current testing equipment is used to inspect conductive materials for surface and near-surface defects without damaging the part. Common applications include detecting cracks, corrosion, erosion, pitting, wall loss, thickness changes, and bolt hole defects in industries such as aerospace, automotive, manufacturing, and power generation.

What industries use eddy current equipment?
Eddy current equipment is widely used across industries like aerospace, oil and gas, manufacturing, automotive, and power generation industries. It is commonly used to inspect aircraft fastener holes, heat exchanger tubes, welds, pipelines, rail components, and other metal structures.
What materials can an eddy current tester inspect?
An eddy current tester can inspect electrically conductive materials, including aluminum, stainless steel, titanium, copper, brass, and carbon steel. Because eddy current testing relies on electromagnetic induction, it cannot be used on nonconductive materials such as plastics or ceramics.
