Product Overview

TheSonic India PAUT A14 Series COD Wedges are developed for phased array ultrasonic testing applications where the wedge must contact the outside diameter of a curved component and support circumferential inspection orientation. This configuration is suitable for pipe welds, pressure vessel welds, cylindrical shell welds, nozzle welds, headers, and other round components requiring OD curved surface inspection.

The COD wedge 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. Stable wedge contact is important for maintaining consistent ultrasonic transmission and reliable inspection data quality.

Manufactured from high-quality Rexolite material, the A14 Series COD Wedge supports efficient ultrasonic sound transmission, dimensional stability, and dependable acoustic performance. 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 unwanted wedge reflections, internal noise, and signal disturbance.

Detailed Product Description

The PAUT A14 Series COD Wedge from TheSonic India is designed for circumferential outer-diameter weld inspection using A14 Probe Series phased array probes. This wedge is selected when the probe and wedge arrangement must follow the outside curved profile of a pipe, vessel, shell, nozzle, or cylindrical component.

The COD wedge differs from the AOD wedge because COD supports circumferential OD inspection, while AOD supports axial OD inspection. Selecting the correct wedge orientation is important for curved component inspection because the contact profile must match the surface geometry and scanning requirement. The COD profile helps maintain stable seating around the outer curved surface, supporting improved coupling and steady probe orientation.

The Rexolite wedge body supports effective ultrasonic energy transfer into the test component. The high-standard damping support helps control unwanted ultrasonic sound paths inside the wedge and supports cleaner, more reliable PAUT inspection data.

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 cylindrical 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 where applicable

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

Suitable Inspection Areas

The PAUT A14 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 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.
