Improved Flaw Detection Method (249)
Comparison of SAFT (black circles) and conventional (open circles) ultrasonic inspection results. Blue arrows indicate flaw size estimation errors for conventional method. Red line indicates machined flaw size.
Problem: Need high resolution flaw characterization in hard-to-inspect locations for vessels and piping
Project Activity Scope (from Technical Overview Chart): Interation Mechanisms through Integrated Systems
PNNL Solution:
- Developed ultrasonic Synthetic Aperture Focusing Technique (SAFT) to inspect materials
- Demonstrated that SAFT method significantly improves inspection reliability for non-homogeneous, coarse-grain materials
- Validated operation on a broad range of reference and test samples
Capabilities Employed to Meet Client Needs: ultrasonic, embedded software (data acquisition, transmission, and storage, visualization, user interface), system integration.
