Product Overview

TheSonic India PAUT A3 Series AOD Wedges are developed for phased array ultrasonic testing 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 shell welds, nozzle areas, headers, and other external cylindrical inspection surfaces.

The AOD contact profile is matched to the outside curved surface, helping maintain stable seating and consistent couplant distribution while the probe moves along the component length. This supports repeatable ultrasonic response, cleaner data acquisition, and improved inspection reliability.

Manufactured from high-quality Rexolite material, the AOD wedge provides stable ultrasonic transmission and industrial durability. High-standard damping material is incorporated to absorb, control, and divert unwanted ultrasonic energy, helping reduce wedge noise, internal reflections, and signal disturbance.

Working Principle / Technology Overview

In AOD inspection, the wedge sits on the component outer diameter while the scan direction follows the axial length of the component. This geometry helps maintain correct probe seating, beam orientation, and couplant behavior during axial movement.

The OD curvature matching is important because a flat wedge may not sit properly on curved surfaces. Correct AOD wedge design helps improve ultrasonic beam entry, coupling stability, and encoded PAUT data quality during pipe and vessel inspection.
