What is Non-Destructive Testing?

June 29, 2017

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

Traditional NDT Technique Comparison

 

NDT-RAM™ is short for Resonant Acoustic Method Nondestructive Testing.  NDT-RAM is Resonant Inspection (RI) for nondestructive detection of structural differences in parts.

Industries that benefit from NDT-RAM:
