Non-Destructive Testing (NDT) is a critical technique used to inspect, test, or analyse materials and assemblies for discontinuities without causing damage. This ensures that the samples can be used even after the testing is complete, saving both time and money.

Why Choose NDT?

NDT is preferred over destructive testing methods as it determines discontinuities that can affect the characteristics of a material without compromising its integrity.

This technique is particularly valuable in industries where preserving the sample is essential.

NDT Testing Methods

• Liquid Penetrant Testing: Applies liquid dye to surfaces to reveal cracks under UV light or without UV light.
• Ultrasonic Testing: Uses high-frequency sound waves to detect internal flaws.
• Radiography: Utilizes X-rays or gamma rays to produce images of internal structures.
• Magnetic Particle Testing: Detects surface and near-surface discontinuities in ferromagnetic materials.
• Visual Testing:  A technique for detecting Surface defects using the naked eye or with magnifying glass.
• Ultrasonic Thickness: A non-destructive testing method used to measure the metal thickness of piping, pressure vessel, tank, structural steel, and others.
• Holiday Testing: A holiday test is an inspection method used to detect discontinuities in painted/coated surface.
• Radiation Testing: Determine radioactivity by measuring the energy emitted by the radioactive atoms present in the items and then "count them up.
