Product Overview

TheSonic India Dual-Array PAUT A27 Series AOD Wedges are designed for phased array ultrasonic weld inspection where the dual-array PAUT probe is positioned on the outside diameter of a curved component and scanning is performed along the axial direction. This wedge configuration is suitable for pipe welds, vessel welds, cylindrical shells, nozzles, headers, and other OD curved inspection surfaces.

The AOD wedge geometry is selected when the wedge must match the outer curved profile of the component while supporting movement along the component length. Proper OD curvature matching helps maintain stable probe seating, consistent couplant behavior, and reliable ultrasonic transmission during PAUT inspection.

Manufactured from high-quality Rexolite material, the A27 Series AOD Wedge supports efficient ultrasonic sound transmission and dimensional stability. The wedge is supported with high-quality, high-standard damping material designed with a zero-tolerance approach toward unwanted ultrasonic sound acceptance. This damping support helps absorb, control, and divert unwanted ultrasonic energy, reducing internal reflections, wedge noise, and signal disturbance during inspection.

Detailed Product Description

The Dual-Array PAUT A27 Series AOD Wedge from TheSonic India is developed for axial outer-diameter weld inspection using A27 Probe Series dual-array phased array probes. The AOD configuration is used when the wedge needs to sit on the outside diameter of a curved component and support scanning along the length of the component.

Compared with a flat wedge, the AOD wedge includes an OD-matched contact profile to improve seating on curved external surfaces. This helps reduce unstable probe movement, improves couplant consistency, and supports repeatable ultrasonic response. In pipe and vessel inspection, stable wedge positioning can directly influence PAUT data quality and inspection reliability.

The Rexolite wedge body supports efficient ultrasonic energy transfer from the probe into the test material. The high-standard damping support helps manage unwanted sound paths within the wedge, reducing unnecessary echo response and improving signal clarity during inspection.

AOD Wedge Application

The AOD Wedge configuration is recommended for outer-diameter curved surfaces where the inspection direction is axial. It is commonly used when the dual-array PAUT probe and wedge are required to travel along the length of a pipe, vessel, shell, nozzle, or cylindrical component.

AOD is different from COD because AOD supports axial OD inspection, while COD supports circumferential OD inspection.

Typical Applications

·       Dual-array PAUT weld inspection on axial OD curved surfaces

·       Pipe weld inspection from outside diameter

·       Vessel shell weld inspection

·       Pipeline fabrication weld inspection

·       Pressure component weld inspection

·       Nozzle and cylindrical connection inspection

·       Boiler header and round component inspection

·       Refinery, petrochemical, and power plant inspection

·       Manual phased array ultrasonic testing on curved OD surfaces

·       Scanner-assisted PAUT inspection where applicable

·       Fabrication, maintenance, shutdown, and in-service inspection

Suitable Inspection Areas

The Dual-Array PAUT A27 Series AOD Wedge is suitable for pipes, vessels, shells, nozzles, headers, and cylindrical components where outside-diameter curvature matching is required and the scanning direction follows the axial length of the component.

For flat surfaces, the Flat Wedge configuration is recommended. For circumferential OD inspection, COD Wedge may be selected. For inner-diameter inspection, AID or CID configurations may be required.
