Eddy current testing is a non-destructive testing method that is applicable for a variety of purposes. This includes detection of cracks, material and coating thickness measurement, and material identification. The process is based on the characteristic known as electromagnetic induction. Any changes in the material conductivity such as near surface anomalies and thickness differences affects the current and voltage flowing in the coil. Thus, that is the foundation of the eddy current testing method.
• Able to detect corrosion, wear and tear, and large porosities
• Probes do not have to be in contact with inspected specimen
• Parts to be tested require minimal preparation

Eddy current testing is a proven method for detecting flaws in conductive metal structures such as copper, aluminium, and steel.
Ideally, eddy current testing should be carried out every 3 to 5 years. If there is active damage occurring needed to be monitored, the test should be carried out more frequently.
Eddy current testing utilises electromagnetic induction to detect and characterise surface and sub-surface flaws in conductive materials. The defects will cause a change in eddy current and a corresponding change in the induction coil used.
Eddy current testing is commonly used for surface inspection and tubing inspection. Surface inspection is widely used in the aerospace and petrochemical industry and can be performed on ferromagnetic and non-ferromagnetic materials. On the other hand, tubing inspection is known as the conventional eddy current testing and is limited to non-ferromagnetic tubing.
