Course description

This course is intended for anyone looking to expand their Eddy Current knowledge, particularly as it applies to aerospace and aviation theory and application.  
Topics covered include: 

  • Aerospace product technology
  • Basic principles of eddy currents
  • Factors affecting eddy currents
  • Coils and probe design
  • Practical eddy currents
  • Electrical theory
  • Basic test set circuits
  • Phase analysis
  • Practical impedance plane analysis
  • The writing of reports and development of procedures
  • Modulation analysis
  • Bolt and fastener hole inspection using rotating probe equipment
  • Latest developments in eddy current technology

During the course, students will learn how to: 

  1. List the types of discontinuities detected with the eddy current test method
  2. Describe the cause and effect of various types of discontinuities
  3. Describe the operational steps in the eddy current test and understand the importance of each step following a written procedure
  4. Interpret and evaluate the test results with respect to the applicable standards
  5. Complete the required test reports, and prepare a clear and concise written instruction (Procedure)
  6. Locate discontinuities in various aircraft materials, components and structures with a probability of detection


This course is compliant with the requirements of EN4179 and NAS410 for the training of Eddy Current inspectors. 

NOTE: In addition to the online training, supplemental reading recommendations are encouraged, especially for those who may be pursuing a career in this rapidly expanding technology.
