Product Overview

TheSonic India TOFD COD Wedges are developed for TOFD applications where the wedge must contact the outside diameter of a curved component and support circumferential inspection orientation. The COD configuration is suitable for pipe welds, vessel welds, cylindrical shell welds, nozzle welds, headers, and round components requiring outside-diameter curvature matching.

The COD profile helps the wedge follow the circumferential shape of the component, improving probe stability and coupling consistency. This supports dependable TOFD data collection during circumferential weld inspection, where stable probe spacing and sound path control are essential.

Manufactured from high-quality Rexolite material, the TOFD COD Wedge supports efficient ultrasonic transmission and dependable acoustic performance. High-quality damping support is included to control, absorb, and divert unwanted ultrasonic energy, helping reduce unwanted internal reflections, wedge noise, and signal disturbance.

Detailed Product Description

The TOFD COD Wedge from TheSonic India is designed for circumferential outer-diameter weld inspection using Time-of-Flight Diffraction ultrasonic testing. 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 AOD because COD supports circumferential OD inspection, while AOD supports axial OD inspection. Correct wedge orientation is important because the contact profile must match both the surface geometry and the scan direction. The COD profile helps maintain steady seating around the external curved surface, supporting consistent coupling and stable TOFD signal response.

The Rexolite wedge body supports effective ultrasonic energy transfer, while the damping support helps control unwanted sound paths within the wedge. This combination supports cleaner data and improved inspection repeatability.

COD Wedge Application

The TOFD COD Wedge 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 around the circumference.

Typical Applications

·       Circumferential TOFD weld inspection on OD curved surfaces

·       Pipe and vessel circumferential weld inspection

·       Cylindrical shell weld inspection

·       Pipeline and pressure component inspection

·       Nozzle and header weld inspection

·       Refinery and petrochemical plant weld inspection

·       Power plant and process piping inspection

·       Scanner-assisted TOFD weld inspection
