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 is consistent thickness - measurements in 1 second
If material is variable thickness - measurements in 1 minute |  |
| | Karl Deutsh Nodularity Meter 1075 Procedure: - Measure with vernier caliper
- Measure with probe
- Velocity displayed with Hi/Lo
Alarm Measurements in 5-10 seconds - Data Processing Available
|
| Sonotest-Atlantic Autoscan 2500L Procedure: - Enter material thickness
- Measure with probe
- Velocity displayed with Hi/Lo
Alarm Features: - Dry Coupling
- Suitable for manual or in-line spot testing of components of known thickness.
- Direct reading of acoustic velocity
- Alarm and value analog outputs allow integration into a variety of inline systems for automatic control in different modes.
Measurement time 1-2 seconds | |
| | Sonotron Isonic 2005 Nodularity Features: - Measure with probe tipped vernier caliper
- Pulse Echo or Thru-Transmission Modes available
- Signal quality displayed with
velocity and go/no go alarm - Data processing capabilities
available Measurements in 1-2 seconds |
| 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 and the part is stamped.
- If Bad a Red Light and the part is not stamped.
Manual Load/Unload Typical production rate is 600 parts per hour. | |
| | American NDT Kicker 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 and the part is stamped.
- If Bad a Red Light and the part is not stamped.
- Manual Load
- Automatic Unload into Good/Bad baskets.
Typical production rate is 900-1200 parts per hour. |
