Uses high-frequency sound waves to detect internal flaws in materials.

Radiographic Testing (RT)

Employs X-rays or gamma rays to examine the internal structure of objects.

Magnetic Particle Testing (MT)

Utilizes magnetic fields to identify surface and near-surface defects in ferromagnetic materials.

Liquid Penetrant Testing (PT)

Involves applying a liquid with high surface wetting characteristics to penetrate surface-breaking defects.

Eddy Current Testing (ET)

Applies electromagnetic induction to detect surface and sub-surface flaws in conductive materials.
