What is Non-Destructive Testing?Overview of NDTDescription
Non-Destructive Testing (NDT) is the examination of an object or material with technology that does not affect its future usefulness. NDT can be used without destroying or damaging a product or material. As it allows inspection without interfering with a product's final use, NDT provides an excellent balance of quality control and cost-effectiveness.
The term "NDT" includes many methods that can:
· Detect internal or external imperfections
· Determine structure, composition or material properties
· Measure geometric characteristics
NDT can and should be used in any phase of a product's design and manufacturing process, including materials selection, research and development, quality assurance and production.
Different Types of NDT Methods
- Resonant Inspection (RI)
- Radiography X-ray (RT)
- Magnetic Particle Testing (MPI)
- Ultrasonic Testing (UT)
- Electromagnetic Eddy Current (ET)
- Acoustic Emission Testing (AE)
- Liquid Penetrant Testing (PT)
- Optical Testing
- Visual Inspection
