Surface and near-surface discontinuity detection in suitable ferromagnetic materials.
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
Surface and near-surface discontinuity detection in suitable ferromagnetic materials.
Core testing ideas
Magnetic fields interact with discontinuities and can create detectable leakage fields.
The method is limited to suitable ferromagnetic materials.
Field direction, geometry and surface condition affect 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.
