Non-Destructive Testing or Evaluation (NDT/NDE) involves the examination of machinery or components to identify surface or internal defects using techniques that will not impair the test items functionality.
NDT Methods
- Visual examination
- Leak detection
- Radiography (X-Rays)
- Ultrasonic thickness
- Gauging
- Magnetic particle
- Inspection
- Hydrostatic testing
- Ultrasonic flaw detection and sizing
- Hardness testing
- Dye penetrant
NDT Applications
Integrity tests on:
- Welds
- Castings
- Forgings
- Extruded, drawn or rolled products
- and during metallurgical testing and failure investigation of industrial products
Condition Monitoring on:
- Shafts
- Machinery parts
Other uses:
- During welder qualifications
