Employs electromagnetic radiation (X-rays or gamma rays) to view the internal structure of an object. Ideal for inspecting weld quality and internal defects.

Analyzes the vibrational characteristics of a material or structure. Used to detect imbalance, misalignment, wear, or insufficiently secured parts.

Involves applying a liquid with high surface wetting characteristics to the surface. Any flaw open to the surface is filled by the liquid, which is drawn out by a developer to reveal the defect.

Uses infrared imaging to evaluate the thermal performance of a material or structure. Variations in thermal conductivity can indicate flaws such as delamination or water intrusion.

Uses magnetic fields to locate surface and near-surface discontinuities in ferromagnetic materials. Indications of a flaw can be visually detected with iron particles.

The most basic form of NDT, it involves the use of a trained eye to identify defects such as misalignments, corrosion, and physical damage.

Determines the presence or absence of leaks in parts that are expected to be airtight or watertight by using techniques like pressure change, bubble, or halogen diode detection.

Uses high-frequency sound waves to detect internal flaws or to characterize materials. Commonly used for evaluating the thickness of materials and detecting flaws such as cracks and delamination.

Monitors the release of kinetic energy from a material undergoing stress (sound waves emitted from cracks propagating). Used for process control, quality control, and safety monitoring.
