Product Overview

TheSonic India PAUT A15 Series AOD Wedges are specially designed for A15 Probe Series phased array ultrasonic testing applications where compact wedge geometry and outer-diameter curvature matching are required. The AOD configuration is used when the inspection contact surface is on the outside diameter of a curved component and the scanning direction follows the axial length of the pipe, tube, vessel, nozzle, or cylindrical part.

The A15 Series is suitable for small-bore pipe weld inspection, restricted-access weld areas, compact components, and applications where a smaller phased array wedge profile is preferred. The AOD curved contact design helps the wedge sit more securely on the OD surface, improving contact stability and ultrasonic coupling during axial weld scanning.

Manufactured from high-quality Rexolite material, the A15 Series AOD Wedge supports reliable ultrasonic transmission, dimensional stability, and dependable acoustic performance during PAUT inspection. The wedge is also 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 unnecessary internal reflections, wedge noise, and signal disturbance during inspection.

Detailed Product Description

The PAUT A15 Series AOD Wedge from TheSonic India is developed for accurate phased array ultrasonic weld inspection on axial outer-diameter curved surfaces. This wedge is selected when the PAUT probe must be positioned on the outside surface of a small-bore pipe, tube, nozzle, vessel, or cylindrical component and moved along the axial direction of the component.

Unlike a flat wedge, the AOD wedge includes a curved bottom profile to suit the outside diameter of the inspected component. This curved contact surface helps improve wedge seating, reduce unstable movement, and support consistent couplant contact during inspection. This is especially important for small-bore pipe welds and compact curved surfaces where probe stability can directly affect inspection data quality.

The compact A15 wedge design is useful for inspection areas where larger wedge bodies may not provide convenient access. It supports practical handling during weld inspection of small-diameter components, pipe spools, process piping, nozzle welds, and restricted areas. The wedge helps guide ultrasonic sound from the phased array probe into the test material while maintaining controlled beam entry and repeatable inspection performance.

The Rexolite wedge body supports efficient ultrasonic energy transfer from the probe into the component. To improve inspection signal quality, the wedge includes high-standard damping support designed to control unwanted ultrasonic sound paths. This helps reduce unnecessary internal echo response and supports cleaner, more reliable PAUT inspection data.

AOD Wedge Application

The AOD Wedge configuration is recommended for outer-diameter curved surfaces where the inspection requirement is axial. It is commonly used when the wedge needs to sit on the outside surface of a pipe, tube, nozzle, or cylindrical component and support scanning along the length of the component.

This configuration is different from Flat, COD, AID, and CID wedge types. AOD is selected when the inspection contact surface is on the outer diameter and the wedge orientation or scanning requirement follows the axial direction of the component.

Typical Applications

·       PAUT weld inspection on axial OD curved surfaces

·       Small-bore pipe weld inspection

·       Tube and pipe spool weld inspection

·       Nozzle weld inspection where AOD geometry is required

·       Compact cylindrical component inspection

·       Process piping weld inspection

·       Boiler tube and header connection inspection where applicable

·       Restricted-access weld inspection

·       Fabrication and site-based weld inspection

·       Manual phased array ultrasonic testing on OD curved surfaces

·       Scanner-assisted PAUT weld scanning where suitable

·       Industrial quality control, maintenance, and shutdown inspection applications

Suitable Inspection Areas

The PAUT A15 Series AOD Wedge is suitable for small-bore pipes, tubes, nozzles, compact cylindrical parts, pipe spools, process piping welds, and outer-diameter curved weld inspection zones. It is useful where the inspection surface requires OD curvature matching and the scanning direction follows the axial length of the component.

For flat surfaces, the Flat Wedge configuration is recommended. For circumferential OD inspection, COD wedge configuration may be selected. For inner-diameter curved surface inspection, AID or CID wedge configurations may be required depending on inspection direction and access condition.
