Phased array (PA) development origins began in the 60’s, with the first commercial units appearing in the medical field in the early 70’s. The 80’s brought the first industrial testing systems although they were extremely large and required data transfer to a computer to be able to complete the processing and image presentation.
These systems were most typically used for in-service power generation inspections. In large part, this technology was pushed heavily in the nuclear market, where critical assessment more greatly allows use of cutting edge technology for improving probability of detection. Other early applications involved large forged shafts and low pressure turbine components.
Current Uses:
- Weld Inspection
- Crack Propagation Inspection
- Corrosion Mapping
- Corrosion Monitoring
