Nondestructive testing (NDT) is the process of inspecting, testing, or evaluating materials, components or assemblies for discontinuities, or differences in characteristics without destroying the serviceability of the part or system. In other words, when the inspection or test is completed the part can still be used.

The most frequently used test methods are

• Magnetic Particle Testing

• Liquid Penetrant Testing

• Radiographic Testing

• Ultrasonic Testing

• Electromagnetic Testing

• Visual Testing

• Acoustic Emission Testing

• Guided Wave Testing

• Laser Testing Methods

• Leak Testing

• Magnetic Radiographic Testing

• Neutron Radiographic Testing

• Thermal / Infrared Testing

• Vibration Analysis
