Eddy Current Testing
Electromagnetic inspection of conductive materials and selected surface or tubing conditions.
Safety boundary: this page is conceptual. It does not provide ionizing-radiation source handling, pressure-test procedures, hazardous chemical recipes, energized test instructions, machine settings or robot operation.
What this topic covers
Electromagnetic inspection of conductive materials and selected surface or tubing conditions.
Core testing ideas
Alternating magnetic fields induce currents in conductive materials.
Discontinuities, geometry and material-property changes alter the measured response.
Probe design and calibration determine sensitivity.
Measurement and method limits
Method capability depends on material, geometry, access, surface condition, calibration and operator competence.
Evidence and traceability
Indications require interpretation and comparison with approved acceptance requirements.
Using the result
Hazardous radiation, pressure, chemicals and machine-operation details are intentionally excluded.
