Automated PAUT Scanners: Enhancing Repeatability, Accuracy, and Performance 

Automated Phased Array Ultrasonic Testing (PAUT) scanners provide consistent, reliable scans. By automating the scanning process, many of the variables associated with manual inspections can be eliminated. By using robotic arms or other automated mechanisms to move the probes across the inspection surface, these scanners ensure that every scan is carried out in the same precise manner every time.

This automation also allows for faster, more consistent results, especially in high-throughput environments. Industries that rely on high-quality standards, such as aerospace and manufacturing, can benefit significantly from these systems, where tolerances are tight and the consequences of defects can be catastrophic. Industries where access is difficult or may require  scaffolding, lift trucks, or rope access—benefit from reduced need for access equipment and improved inspection consistency in challenging environments.

Applications of Automated PAUT Scanners

Weld Inspections

• Pressure Vessels, Piping, and Tubing: PAUT is used to inspect welds in these components for defects like cracks and flaws, ensuring structural integrity.
• Small-Diameter Weld Inspection: PAUT can inspect welds in small-diameter stainless steel pipes, which can be challenging due to material and geometry.
• Boiler Tube Inspection: PAUT helps detect flaws in boiler tubes, including hydrogen damage, which is crucial for safety in high-temperature environments.

Crack Detection

• HIC, SOHIC, and SCC: PAUT is used to detect various types of cracking, including hydrogen-induced cracking (HIC), stress corrosion cracking (SCC), and stress-oriented hydrogen-induced cracking (SOHIC).

Corrosion Detection

• Corrosion Mapping: PAUT helps map and quantify corrosion damage on assets like storage tanks, pipelines, and other critical infrastructure.

Flaw Sizing and Material Characterization

• Remaining Life Calculations: PAUT helps determine the remaining life of components by accurately sizing flaws.
• Material Property Assessment: PAUT can detect changes in material properties, such as hardness or grain size.

Other Applications

• Wind Turbine Blade Inspection: PAUT is used to inspect wind turbine blades for defects like delaminations and cracks.
• Composite Material Inspection: PAUT can inspect composite materials for defects.
• Automated Robotic Inspections: PAUT can be integrated into robotic systems for automated inspections in hazardous or difficult-to-access environments.
• Underwater Inspections: PAUT can be used in underwater inspections, such as those of pipelines or offshore structures.
• Joint and Interface Inspection: PAUT is used to inspect joints and interfaces, for example, to detect adhesive.

Why Automation Increases Repeatability and Accuracy

When we talk about NDT, consistency is key. Automated PAUT scanners help ensure the same scanning technique is applied every time, minimizing human error. This level of repeatability means that in-service inspections can be compared more effectively over time, ensuring the integrity of parts and structures is monitored more accurately.

Automation also allows for higher scan rates, improving throughput without sacrificing quality. It’s especially useful in high-demand industries like aerospace and automotive, where large volumes of parts must be inspected quickly and consistently.

In addition to repeatability, automated systems also improve accuracy. Human operators, even skilled ones, can vary the scanning technique depending on fatigue, distractions, access, or other physical limitations. Automated systems eliminate these variables, ensuring that every part of the inspection is executed to the same high standard every time.

The Key to Better Performance: The Probes

While automated scanners offer the benefits of repeatability and accuracy, they are only as good as the probes they are using. The accuracy, stability, and reliability of the probes are critical to achieving optimal performance. Vermon NDT's probes, designed with precision and stability in mind, are the key to unlocking the full potential of automated PAUT scanners.
