Product Overview

TheSonic India PAUT A2 Series AOD Wedges are developed for phased array ultrasonic weld inspection where the probe is positioned on the outside diameter of a curved component and scanning is performed in the axial direction. This wedge configuration is suitable for pipe welds, vessel welds, cylindrical shells, nozzles, headers, and similar OD curved inspection surfaces.

The AOD wedge geometry is designed to improve contact stability on curved outer surfaces. During PAUT inspection, proper wedge seating is important because uneven contact may affect coupling, beam entry, and signal consistency. The A2 Series AOD Wedge helps maintain controlled ultrasonic transmission from the phased array probe into the test material while supporting smooth axial movement along the component length.

Manufactured from high-quality Rexolite material, this wedge offers dependable ultrasonic transmission and dimensional stability for industrial NDT applications. It 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 unnecessary internal reflections, wedge noise, and signal disturbance.

Detailed Product Description

The PAUT A2 Series AOD Wedge from TheSonic India is designed for axial outer-diameter weld inspection using A2 Probe Series phased array probes. The AOD configuration is selected when the scanning surface is the outside diameter of a round component and the probe movement follows the component’s axial direction.

Unlike flat wedges, the AOD wedge includes OD curvature matching to improve seating on curved surfaces. This helps the wedge remain stable during scanning and supports more consistent couplant behavior. In industrial weld inspection, especially on pipes and pressure components, stable wedge contact can improve data repeatability and reduce unnecessary coupling variation.

The Rexolite wedge body supports effective ultrasonic energy transfer from the probe to the test component. The high-standard damping arrangement is included to manage unwanted sound paths inside the wedge. By reducing unwanted reflections and signal disturbance, the wedge supports cleaner inspection data and more dependable PAUT evaluation.

AOD Wedge Application

The AOD Wedge configuration is recommended when the inspection contact surface is located on the outside diameter and the inspection direction is axial. It is commonly selected for weld inspection where the probe and wedge need to move 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

·        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 cylindrical component inspection

·        Refinery, petrochemical, and power plant inspection

·        Field inspection and shutdown maintenance inspection

·        Manual PAUT and scanner-assisted PAUT scanning

·        Industrial fabrication and in-service inspection

Suitable Inspection Areas

The PAUT A2 Series AOD Wedge is suitable for pipes, vessels, shells, nozzles, headers, and cylindrical components where OD curvature matching is required and the inspection direction follows the axial length of the component.

For flat surfaces, Flat Wedge is recommended. For circumferential OD inspection, COD Wedge may be selected. For ID inspection applications, AID or CID configurations may be required.
