ET-Eddy Current Testing

Course details

Eddy current testing method is used for testing of the electrically conductive materials. This method is applicable in wide scale of branches, very often used for inspections of metallurgic semi-products during the in-service inspections of pipe type heat exchangers and in aerospace and automotive industry. This method is widely used for surface discontinuities detection. The discontinuities can be detected to specific depth under surface. This method allows measuring thickness of nonconductive coating or selecting the different materials on the base of the difference in the chemical composition or heat treatment.

What you will learn

Participant will be trained in inspection according to applicable codes and specifications, and learn to develop procedures for your applications. The Level 2 certified specialist is responsible for testing and evaluating the findings according to SNT-TC-1A or EN 473 standard. They can develop the NDT instructions and manage ET testing for their workplace.
