Non destructive testing

The thorough inspection of components is a way to check that each component is defect free, or complies with certain quality requirements to retain their usability.

Where necessary, 100% of production can be inspected in real time, removing outliers from your production without adding to your production cycle time.  The various NDT techniques include:
  • ultrasonic inspection
  • Eddy current testing
  • magnetic particle inspection
  • resonant inspection
