Eddy Current Testing (ECT) - ASNT Level II Verified Partner

Deskripsi / Persyaratan

When a magnetic field cuts through metal, a current is induced. If a magnetic field cuts a wire in a closed circuit, a current is induced round the circuit. However if a magnetic field cuts through a sample of metal that is not connected to a circuit, an Eddy Current is produced. This eddy current is localized in the metal and has a flow pattern. The flow pattern is disturbed by discontinuities from the surface to a shallow depth of penetration. The method is quick and very sensitive. No contact with the metal is required. All metals may be subject to this form of testing.

This course is orientated towards candidate NDT inspectors.
