Eddy Current Testing Equipment
Eddy current testing is used to find surface cracks and corrosion in metal parts, welds and aircraft structures, without damaging them. Asia NDE supplies eddy current flaw detectors, eddy current probes and reference standards from ETher NDE across Malaysia and Southeast Asia. We serve aerospace, oil and gas, petrochemical, railway and fabrication customers, with calibration and repair support from our Subang Jaya office.
What it’s used for
- Finding surface and near-surface cracks in aircraft structures, engine parts and wheels.
- Inspecting welds for cracks through paint and coatings, including on rope access work.
- Checking rail heads for surface defects and head checks.
- Detecting and sizing cracks with alternating current field measurement (ACFM).
- Finding corrosion and measuring conductivity in non-ferrous metals.
How eddy current works
An eddy current probe carries an alternating current. This sets up small circulating currents, called eddy currents, in the metal under the probe. A crack or loss of metal disturbs these currents, and the eddy current flaw detector shows the change on screen. The probe does not need bare metal or a liquid couplant.

Frequently asked questions
What is eddy current testing used for?
Eddy current testing is used to find surface and near-surface cracks and corrosion in metals that conduct electricity. Typical jobs include aircraft structure and wheel inspection, weld inspection through paint, rail inspection, heat exchanger tube inspection, and checking alloy or heat treatment by measuring conductivity.
How is eddy current different from ultrasonic testing?
Eddy current testing uses electromagnetic induction and is best for cracks at or near the surface of conductive metals. It needs no couplant and can work through paint. Ultrasonic testing uses high-frequency sound to find flaws deeper inside a part and to measure wall thickness, and it needs a couplant such as gel.
Do you calibrate and repair this equipment?
Yes. Asia NDE runs a manufacturer-approved calibration centre, with repair support in Malaysia, for the eddy current equipment we supply. Send us the model and serial number and we will arrange calibration or a repair.
