Product Overview
TheSonic India PAUT A2 Series COD Wedges are designed for phased array ultrasonic testing applications where the wedge must contact the outside diameter of a curved component and support circumferential inspection orientation. This wedge type is suitable for OD weld inspection on pipes, pressure vessels, cylindrical shells, nozzles, headers, and other round components.
The COD configuration is selected when the inspection arrangement requires the wedge to follow the circumferential profile of the component. Its OD curved contact surface helps improve seating, coupling stability, and probe control during PAUT weld inspection. This is important for inspection applications where the probe must maintain reliable contact while positioned around the outside diameter of the component.
Manufactured from high-quality Rexolite material, the A2 Series COD Wedge supports efficient ultrasonic sound transmission and reliable acoustic performance. The wedge is also 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 and improving inspection signal clarity.

Detailed Product Description
The PAUT A2 Series COD Wedge from TheSonic India is developed for circumferential outer-diameter phased array weld inspection. This wedge is used when the inspection surface is located on the outside diameter of a cylindrical component and the required wedge orientation follows the circumferential direction.
The COD wedge differs from the AOD wedge because COD is intended for circumferential OD applications, while AOD is intended for axial OD inspection. This distinction is important when selecting the correct wedge geometry for pipe, vessel, shell, or nozzle inspection. The COD contact profile helps the wedge sit correctly on the external curved surface, supporting improved coupling and stable sound entry.
The Rexolite wedge body provides dependable ultrasonic transmission, while the high-standard damping support helps control unwanted sound energy inside the wedge. This combination supports more stable PAUT data collection, reduced wedge noise, and consistent inspection performance.
COD Wedge Application
The COD Wedge configuration is recommended for outer-diameter curved surfaces where the inspection requirement is circumferential. It is commonly used when the wedge must sit on the outside surface of a round component and support inspection orientation around the circumference.
COD is different from AOD because COD supports circumferential OD inspection, while AOD supports axial OD inspection.
Typical Applications
· PAUT weld inspection on circumferential OD curved surfaces
· Pipe and vessel circumferential weld inspection
· Cylindrical shell weld inspection
· Pipeline and pressure component inspection
· Nozzle and pipe connection weld inspection
· Boiler header and curved component inspection
· Refinery and petrochemical plant weld inspection
· Power plant and process piping inspection
· Manual phased array ultrasonic testing
· Scanner-assisted PAUT inspection
· Fabrication, maintenance, shutdown, and in-service inspection
Suitable Inspection Areas
The PAUT A2 Series COD Wedge is suitable for OD curved surfaces where circumferential curvature matching is required. It is commonly used for pipes, vessels, shells, nozzles, headers, and other cylindrical components.
For flat surfaces, Flat Wedge is recommended. For axial OD inspection, AOD Wedge may be selected. For internal curved surface inspection, AID or CID configurations may be required.
