Advanced ultrasonic inspection for critical welds & components
Phased Array Ultrasonic Testing (PAUT)
PAUT provides high-resolution imaging and accurate defect sizing to support safe, reliable decision-making. BRIGHT TECH ENGINEERING supports projects across Singapore, Malaysia & SEA with fast mobilisation and clear reporting.
What is PAUT?
Phased Array Ultrasonic Testing (PAUT) uses multiple ultrasonic elements and electronic beam steering to inspect welds and components from many angles—without moving the probe as much as conventional UT.
The result is a detailed cross-sectional view of indications, improved coverage in complex geometries, and reliable sizing to support acceptance criteria and repair decisions.
Why choose PAUT
Key advantages for weld integrity and asset reliability
PAUT is ideal when you need better coverage, clearer imaging, and confident sizing—especially for critical welds and thickness transitions.
High-resolution imaging
Sectorial scans provide a clear view of indications for easier interpretation and review.
Improved coverage
Electronic beam steering helps inspect from multiple angles to reduce missed areas.
Accurate sizing & location
Supports reliable depth/position information to guide repair decisions and acceptance.
Efficient on-site execution
Faster scanning and repeatable setups help minimise downtime where access allows.
Digital data & traceability
Scan data can be stored for audit trails, comparisons, and client review.
Works with complementary methods
Often paired with TOFD/UT/VT to strengthen coverage based on project needs.
Typical applications
Where PAUT is commonly used
We tailor procedures and scan plans to the component, access, and acceptance criteria. Common PAUT use cases include:
Weld inspection
Butt welds, fillet welds, and critical joints in piping, pressure equipment, and structural steel.
Fabrication & construction QA/QC
New build inspections, repair verification, and documentation for project handover.
In-service inspection
Monitoring for cracking, lack of fusion, and other reportable indications during maintenance windows.
Complex geometries
Thickness transitions, restricted access areas, and components where conventional UT coverage is challenging.
How we deliver
Our PAUT workflow
A disciplined process helps ensure consistent results and clear deliverables—aligned to project requirements.
1) Scope & acceptance criteria
Confirm component details, access, drawing/WPS information, and the relevant acceptance criteria and reporting needs.
2) Procedure & scan plan
Select probe/wedge, define focal laws, calibration blocks, and coverage to suit the weld geometry and expected flaw orientation.
3) Calibration & verification
Perform sensitivity/TCG (as applicable), verify index/angle, and confirm system performance before scanning.
4) Scanning, analysis & reporting
Acquire scan data, evaluate indications, and issue a clear report with locations, sizing (where applicable), and recommendations.
