Non-destructive testing (NDT course)

Definition of NDT

The use of noninvasive techniques to determine the integrity of material, compound, structure or quantitatively measure some characteristics of an object i.e. inspect or measure without harm.

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.

There are 6 most frequently used NDT methods, and also many others not so used methods:

• Magnetic Particle testing – MT
• Liquid Penetrant testing – PT
• Radiographic testing – RT
• Ultrasonic testing – UT
• Visual testing – VT
