EDDY CURRENT TESTING FAQ
Open All
An eddy current is a current initiated in a conductor that reacts to a changing magnetic field. Eddy currents flow in closed loops within conductors, in planes perpendicular to the magnetic field, and take the form of eddies such as those that occur in whirlpools. They are used widely in several industries, including manufacturing and aerospace where eddy current inspections are required to reduce safety-related or quality-related problems, such as in thin metal areas.
What is eddy current testing?
Eddy current testing is built on the interaction between a magnetic field source and the test material. This interaction induces eddy currents in the test piece. Material flaws in the test piece cause a change in the eddy currents, and this change can be measured by eddy current testing devices. Such devices, which do not make contact with the test material and are non-destructive, can be used to draw conclusions on the size and nature of the material flaw.
How do you choose the right eddy current testing tool?
The eddy current testing tool you choose depends on the complexity of the test needed. Eddy testing devices range from complex high-performance systems to budget-friendly basic systems. The number of channels and test positions required will affect the cost of the tools. More complex testing usually requires more channels and more test positions.
