Inspection Methods
Major NDT methods
Six commonly used methods are presented as individual modules. Each card links to additional information.
ET
Electromagnetic Testing
Uses electromagnetic induction and related techniques to detect discontinuities in conductive materials.
Open method →MT
Magnetic Particle Testing
Locates surface and near-surface discontinuities in ferromagnetic materials by magnetizing the part.
Open method →PT
Liquid Penetrant Testing
Reveals surface-breaking discontinuities in solid, nonporous materials using visible or fluorescent penetrant.
Open method →RT
Radiographic Testing
Uses X-rays or gamma rays to create images of internal structure and detect internal discontinuities.
Open method →UT
Ultrasonic Testing
Uses high-frequency sound waves to detect and evaluate surface and subsurface discontinuities.
Open method →VT
Visual Testing
Uses direct observation or optical aids to evaluate visible surface conditions and discontinuities.
