Phased Array Ultrasonic Testing (PAUT) drives an array of ultrasonic elements with controlled time delays to sweep a range of angles from a single probe position. The result is a fast, fully encoded and imaged inspection that documents exactly where and how deep each indication sits.
PAUT is increasingly specified as a safer, radiation-free alternative to radiographic testing (RT) for weld examination — no exclusion zone, instant results and a digital record for life-of-asset traceability.
Typical Applications
- Encoded girth and seam weld scans
- Replacement for RT where access or safety limits it
- Corrosion mapping of vessels and tank floors
- Crack sizing and through-wall depth
- Node and complex geometry welds
Why TESKO NDT
- No radiation — work continues around the scan
- Faster coverage than conventional UT or RT
- Permanent, auditable digital scan record
- Accurate flaw height/depth sizing for fitness-for-service
