Course Overview
Eddy current testing, also known as Foucault current testing, uses electromagnetic induction to detect surface and near-surface discontinuities in conductive materials. This course builds practical understanding of alternating magnetic fields, probe response, calibration, and interpretation for industrial inspection work.
Training Course Objective
- Understand how changing magnetic fields induce eddy currents in conductive materials.
- Study how eddy currents respond to material thickness, conductivity, geometry, and discontinuities.
- Learn the role of Lenz's law, opposing magnetic fields, and signal variation in inspection results.
- Use eddy current methods to detect cracks, flaws, and other defects in tubing and fabricated components.
- Build confidence in setup, calibration, scanning, signal interpretation, and reporting.
Key Topics Covered
- Electromagnetic induction fundamentals
- Coils, probes, frequencies, and lift-off effects
- Calibration blocks and reference standards
- Surface crack and flaw detection
- Tubing, weld zone, and component inspection
- Signal analysis, phase, and amplitude review
- Limitations, applications, and inspection reporting
