Phased Array Ultrasonic Testing (PAUT) is an advanced ultrasonic testing method that, thanks to its multi-element probe design, allows the weld and material volume to be scanned electronically from different angles. It can be recorded digitally, offers a high coverage rate and delivers fast results.
Because it involves no radiation, it is used in many applications as an alternative or complementary method to radiographic testing (RT).
Typical Applications
- Pipe circumferential welds
- Pressure vessel welds
- Tank and ship structures
- Thick-walled welds
- Corrosion mapping
- Code-compliant UT applications in place of RT
Why PAUT (Phased Array Ultrasonic Testing)?
- 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
