Ultrasonic Testing (UT) utilizes high-frequency sound waves (0.1-20 MHz) to detect internal volumetric discontinuities. It provides precise data on the depth, size, and nature of internal flaws.
Instructions are prepared by LEVEL 3 expert personnel.
Capabilities
- Internal volumetric defect detection
- Material thickness measurement
- Accurate sizing of sub-surface cracks
Techniques

- Angled probes (45°, 60°, 70°) for weld inspection
- Advanced TOFD and Phased Array options
Limitations
- Coarse-grained materials (Austenitic)
- High sound attenuation in complex alloys
- Surface couplant required for wave transmission
