What Is PAUT
Phased Array Ultrasonic Testing (PAUT) is an advanced method of ultrasonic testing that offers several advantages over traditional single-probe ultrasound techniques.
PAUT utilises a set of ultrasonic probes composed of numerous small elements.
By applying time delays to piezoelectric crystals, PAUT focuses ultrasonic beams at precise depths and angles.
Equipment We Use
How PAUT Works:
Instead of using a single large probe, PAUT employs an array of small individual crystals (transducers). These crystals can send and receive sound waves independently at different times.
By controlling the timing of each crystal, a computer creates a focused and moving ultrasound beam. This beam can scan an object without physically moving the entire probe.
The ability to electronically steer and focus the sound beam allows for precise inspection at various depths and angles within the test object.

PAUT Application
Industries Using PAUT:
PAUT finds applications in various industries, including:
- Construction
- Oil and gas
- Marine
- Power plants
- Aerospace
- Automotive manufacturing
Utilised In:
Weld Inspection:
- PAUT is commonly used for inspecting butt welds in pipes, pressure vessels, and large structures.
Corrosion Mapping:
- It estimates thickness at finite points in pressure vessels, pipes, tanks, and other structures.
Complex Geometries:
- PAUT can scan painted cylindrical or trapezoidal fuel transport tankers and other intricate shapes.
High-Pressure and High-Temperature Piping:
- Inspections at power station sites, focusing on circumferential and seam welds.
Branch Welds and Variable Profiles:
- Accurate sizing of internal defects in complex geometry branch welds.
Turbine and Generator Components:
- Special focus on areas of high stress concentration, such as turbine blade roots.
Shafts, Axles, and Spindles:
- In-site inspection for transverse cracks and precise detection.
Total Focusing Method (TFM) – Defect sizing for remaining life calculations
Robotic Weld Inspection
Advantages of Choosing PAUT
Ease of Use and Mobility
PAUT systems are easier to handle, and maneuverer compared to traditional probes. Technicians can inspect complex geometries without physically repositioning the probe.
Safety
Unlike some other testing methods (such as X-rays), PAUT doesn’t involve radiation exposure.
Accurate Sizing and Mapping
It provides precise defect sizing and mapping capabilities.
Faster Inspections
Electronic scanning enables rapid coverage of large areas, reducing inspection time.
Improved Detection
PAUT can detect internal defects (such as cracks, voids, or inclusions) more effectively than conventional probes.
Customization
PAUT allows for individually tailored development of qualification blocks and specific configurations for data collection and post-analysis reporting.
