Phased Array

What is Phased Array Ultrasonic Testing?

Phased Array Ultrasonic Testing (PAUT) is a highly advanced non-destructive testing (NDT) technique designed to detect flaws and measure thickness within a material. Unlike traditional ultrasonic testing, PAUT uses multiple sound beams that can be electronically steered and focused to provide detailed imaging, making it ideal for complex inspections.

How does Phased Array work?

The process involves the following key steps:

Preparation: The test surface is thoroughly cleaned to remove any contaminants that could interfere with signal quality.
Probe Positioning and Calibration: A specialized phased array probe is positioned on the material’s surface. The probe emits multiple ultrasonic beams, which are calibrated to focus on specific areas or depths.
Electronic Steering of Beams: Unlike conventional UT, PAUT allows the operator to steer the beams electronically, adjusting angles and focus points for a more comprehensive view. This process creates a cross-sectional view of the test material.
Inspection and Evaluation: The ultrasonic waves travel through the material and reflect back to the probe when they encounter flaws or inconsistencies. These reflections are recorded and displayed as real-time images, allowing the inspector to detect and evaluate any flaws with high precision.

Advantages of using Phased Array

High Precision: Phased Array offers exceptional detail, allowing for accurate flaw detection in complex geometries or hard-to-reach areas.
Versatile Application: Suitable for inspecting welds, pipework, pressure vessels, and other critical components.
Real-Time Imaging: Phased Array provides immediate, high-quality images, enabling quick evaluations and on-the-spot decision-making.
Cost and Time Efficient: Phased Array’s ability to detect defects accurately helps avoid costly repairs or component replacements by identifying issues early.
Reduced Radiation Hazard: As Phased Array relies on ultrasonic waves rather than radiation, it presents a safer alternative to testing methods such as Radiography

Applications of Phased Array

Phased Array Ultrasonic Testing is commonly used across various industries for its versatility and detailed imaging capabilities, including:

Aerospace: For testing aircraft components, including fuselages, wing structures, and engine parts.
Oil & Gas: For inspecting pipeline welds, pressure vessels, and structural components.
Petrochemical: Used to examine reactors, heat exchangers, and high-pressure piping.
Power Generation: For checking the integrity of turbine blades, boiler components, and critical welds.
Fabrication: Ideal for testing structural welds, pressure vessels, and critical pipework assemblies.
