Non destructive testing

 
Non destructive testing

Is the inspection of components in a way that ensures that the components are defect free or comply with certain quality requirements in such a way as to retain their usability. This means that where necessary, 100% of production can be inspected in real time, removing outliers from your production without adding to your production cycle time.

Following different NDT techniques are available:

  • Ultrasonic inspection
  • Eddy current testing
  • Magnetic particle inspection
  • Resonant inspection
