About Eddy Current Testing

Eddy current is a Non Destructive Testing method for the inspection of discontinuities located on or near the surface of articles. It uses electrical currents generated in a conductive material by an induced magnetic field to detect imperfections or changes in properties within a material.  Eddy Currents can be very sensitive to small discontinuities and has many applications in modern industry. Types of applications which this can be used with are inspections of welds and aerospace materials as well as conductivity sorting of materials.

Recommended Course Prerequisites

  • Magnetic Particle Inspection
  • Basic Literacy Skills
  • Basic Language Skills
  • Intermediate Maths Skills (Algebra and Trigonometry) 
  • Product Technology and Processes

While not essential, as the course notes do cover all required areas, reading some of the below literature might help provide additional knowledge, and are generally available in reference libraries:

  • Materials and Processes for NDT Technology. ASNT
  • Eddy Current Testing, Classroom Training Handbook (CT-6-5): ASNT. 
  • Non-Destructive Testing Handbook, Volume 4 - Eddy Current Testing. ASNT. 

See our knowledge section to try examples of the typical question and problems that you will encounter during the course.


TCS NDT can offer an extensive range of Eddy Current Inspection Services
