NDT is the process of inspecting, testing, or evaluating materials, assemblies or components for discontinuities, or differences in characteristics without damaging the serviceability of the system or component. Specialized non destructive testing equipment is employed for NDT process. Other tests are destructive in nature as compared to NDT and this is why these tests are done on a limited sample numbers instead of on the materials, assemblies, or components actually being put into service.
The destructive testing methods are often applied when the user needs to determine the physical properties of materials, like-
- Impact resistance
- Yield
- Ductility
- Fracture toughness
- Ultimate tensile strength
- Fatigue strength
However, to determine differences and discontinuities in material characteristics are effectively availed by NDT process.
Today, industries are mostly relying on modern Non-destructive testing equipment methods for manufacturing, fabrication, and in-service inspections to ensure integrity and reliability of the product. They are also using these methods to control manufacturing processes, lower production costs and to maintain a uniform quality level.
During construction, non destructive testing equipments are employed to ensure and check the quality of materials and joining processes during the manufacturing and erection phases.
NDT test methods used by professionals
Test method names refer to the penetrating medium type or the equipment used to carry out that testing method. Some NDT methods used by experts are-
- Acoustic Emission testing
- Electromagnetic testing
- Ground Penetrating Radar
- Laser testing methods
- Leak testing
- Radiographic testing
- Ultrasonic testing
- Vibration Analysis
- Visual testing and more
