Automated Ultrasonic Testing (AUT)
Automated Ultrasonic Testing (AUT)
Automated Ultrasonic Testing (AUT) is an advanced non-destructive testing technique designed to deliver high-speed, consistent, and repeatable inspection results for critical welds and components. At Assessfie, our AUT services combine automated scanning systems with advanced ultrasonic technology to reduce human variability, improve data accuracy, and ensure reliable defect detection and sizing. AUT is particularly effective for large-scale projects requiring uniform inspection quality and detailed digital records.
How Automated Ultrasonic Testing Works
- Automated scanners equipped with ultrasonic probes are positioned on the test surface.
- The scanner moves along the component following a programmed inspection path.
- Ultrasonic signals are collected continuously and recorded digitally.
- Certified AUT inspectors analyze the data to identify defects, determine their size and location, and generate comprehensive inspection reports.
Technologies & Techniques We Use
- Automated Weld Inspection Systems
- Phased Array UT and TOFD Integrated with AUT
- Linear and Circumferential Scanning
- High-Speed Data Acquisition and Recording
- Advanced Imaging and Analysis Software
- Portable AUT systems for field and offshore inspections
AUT Applications in the Oil & Gas Industry
Automated Ultrasonic Testing is widely used across upstream, midstream, and downstream operations, especially where large volumes of welds must be inspected efficiently. Common applications include:
Pipeline Girth Weld Inspection — High-volume inspection of onshore and offshore pipelines
Pressure Vessels & Storage Tanks — Automated inspection of critical weld seams
Fabrication Yards — Quality control for repetitive welds in modules and skids
Offshore & Marine Structures — Consistent weld inspection in jackets and risers
In-Line Projects — Fast inspection with minimal disruption to construction schedules
In-Service Inspection — Reliable monitoring of weld integrity over time
Weld Repair Verification — Objective confirmation of defect removal and weld quality
