Phased Array Ultrasonic Testing (PAUT) is an advanced, non-destructive method using multiple ultrasonic elements to create detailed internal images, replacing slower, radiation-based tests (like RT) for faster, safer inspections, especially for welds, corrosion, cracks, and complex geometries in industries like Oil & Gas, Aerospace, and Power Generation, ensuring structural integrity, quality control, and asset fitness.

Key Applications

• Inspection: Detecting flaws (cracks, porosity, lack of fusion) in welded joints for pipelines, pressure vessels, and structural components.
• Corrosion Mapping : Measuring metal loss and mapping corrosion under insulation (CUI) on pipes and tanks.
• Thickness Measurement : Accurately measuring material thickness, including coatings.
• Crack Detection : Finding cracks in critical parts like train wheels, axles, and turbine blades.
• Complex Geometries & Composites : Inspecting intricate shapes, composite materials, and bonded joints (like in aircraft).

Industries Using PAUT

• Oil & Gas: Pipelines, refineries, petrochemical plants.
• Aerospace: Aircraft structural components, composite parts.
• Power Generation: Boilers, turbines, heat exchangers, nuclear components.
• Manufacturing: General fabrication, automotive.
• Infrastructure & Rail: Bridges, rolling stock (wheels/axles).

Benefits & Advantages

• Detailed Imaging: Provides clear, visual C-scans (cross-sections) of defects.
• Speed & Efficiency: Faster inspections and real-time results.
• Safety: Eliminates ionizing radiation, removing the need for exclusion zones.
• Versatility: Electronically steers beams to inspect from multiple angles with one probe.
• Accuracy: Better flaw sizing, shape, depth, and orientation determination.
