Product Overview

TheSonic India PAUT PWZ1 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 along the axial direction. This configuration is suitable for pipe welds, vessel welds, cylindrical shells, nozzles, headers, and other OD curved inspection surfaces.

The AOD wedge geometry is selected when the wedge must match the outside curved profile of the component while supporting movement along the component length. Proper OD curvature matching helps maintain stable probe seating, consistent couplant behavior, and reliable ultrasonic transmission during PAUT inspection.

Manufactured from high-quality Rexolite material, the PWZ1 Series AOD Wedge supports efficient ultrasonic sound transmission and dimensional stability. 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 internal reflections, wedge noise, and signal disturbance.

Working Principle / Technology Overview

The AOD wedge supports axial scanning on outside curved surfaces. In this arrangement, the wedge contact face is curved to match the external pipe or vessel surface while the scan direction follows the length of the component. This geometry helps keep the phased array probe aligned with the weld scan path and supports consistent beam entry into the material.

The curved OD contact surface helps reduce coupling variation and improves surface contact on cylindrical components. This is important for PAUT inspection because inconsistent coupling or unstable probe angle can affect sector scan response, encoded data quality, and weld flaw detectability.

Detailed Product Description

The PAUT PWZ1 Series AOD Wedge from TheSonic India is designed for axial outer-diameter PAUT weld inspection. Compared with a flat wedge, the AOD wedge includes curvature matching to improve seating on external curved surfaces. This helps reduce unstable probe movement and supports consistent couplant contact.

The AOD wedge is useful where the inspection contact surface is the outside diameter and the scanner or probe must move along the component length. It is commonly applied for pipe welds, vessel shell welds, nozzle areas, and cylindrical components where OD axial inspection is required.

The PWZ1 Series AOD Wedge can be supplied with customized OD curvature, probe mounting, wedge angle, couplant feed, and scanner interface based on inspection requirement.

AOD Wedge Application

The AOD Wedge configuration is recommended for outer-diameter curved surfaces where the inspection direction is axial. AOD is different from COD because AOD supports axial OD inspection, while COD supports circumferential OD inspection.
