NDT Guide to Nodularity Testing

Ultrasonic Testing has been used for many years to sort ductile (nodular) iron castings for proper nodularity based on sound velocity measurements.

There are currently a number of products that we can provide based on your application and budget requirements.

Please review the below short descriptions and call us to discuss your application details and pricing.

Dakota VX
Procedure:
  • Manually enter material thickness
  • Couple probe to material
  • Read velocity value
If material has consistent thickness - measurements in 1 second
If material has variable thickness - measurements in 1 minute

American NDT Nodularity System

Procedure:

  • Insert part in the in tank guide
  • Part thickness and nodularity are measured untrasonically
  • Machine evaluates velocity and if acceptable a Green Light will come on and the part will be stamped.
  • If the machine does not find it acceptable a Red Light will come on and the part will not be stamped.

Manual Load/ Unload

Typical Production rate is 600 parts per hour.
