Product Overview

TheSonic India PAUT PWZ1 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 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.

Manufactured from high-quality Rexolite material, the PWZ1 Series COD Wedge supports efficient ultrasonic transmission, dimensional stability, and dependable acoustic performance. The wedge is supported with high-quality, high-standard damping material to absorb, control, and divert unwanted ultrasonic energy.

Working Principle / Technology Overview

The COD wedge supports circumferential scanning on outside curved surfaces. The curved contact profile is designed to sit on the pipe or vessel OD while the scan orientation follows the circumference of the component.

This geometry helps maintain consistent coupling and stable probe orientation around the external curved surface. In PAUT weld inspection, correct COD wedge selection helps improve beam direction, scan repeatability, and encoded data quality when inspecting circumferential welds or OD curved weld zones.

Detailed Product Description

The PAUT PWZ1 Series COD Wedge from TheSonic India is developed for circumferential outer-diameter weld inspection using PWZ1 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.

COD is different from AOD because COD supports circumferential OD inspection, while AOD supports axial OD inspection. Selecting the correct wedge orientation is important because the contact profile must match both surface geometry and scan direction.

The Rexolite wedge body supports effective ultrasonic energy transfer into the test component. The 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.
