Product Overview

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

The A15 Series is suitable for small-bore pipe weld inspection, restricted-access weld areas, compact component inspection, and applications where a smaller PAUT wedge profile is preferred. The COD curved contact design helps the wedge sit securely on the OD surface while supporting stable ultrasonic transmission during circumferential weld inspection.

Manufactured from high-quality Rexolite material, the A15 Series COD Wedge supports efficient ultrasonic sound transfer, dimensional stability, and dependable acoustic performance during phased array ultrasonic testing. 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 COD Wedge from TheSonic India is developed for phased array ultrasonic weld inspection on circumferential 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 the inspection arrangement requires circumferential OD curvature support.

Unlike a flat wedge, the COD wedge includes a curved contact profile to suit the outside diameter of the inspected component. This helps improve contact stability, reduce unwanted wedge movement, and support consistent couplant behavior during inspection. The compact A15 design is especially useful for smaller pipe diameters, limited-access areas, nozzle welds, and compact curved inspection surfaces where larger wedges may not provide convenient handling.

The COD wedge configuration is different from the AOD version. AOD is generally selected for axial OD applications, while COD is selected for circumferential OD inspection requirements. This makes the A15 COD Wedge suitable for inspection situations where the wedge must follow the curved outer surface around the circumference of the component.

The Rexolite wedge body supports effective ultrasonic energy transfer from the phased array probe into the test material. To improve inspection signal quality, the wedge includes high-standard damping support designed to control and divert unwanted ultrasonic sound paths. This helps reduce unnecessary internal echo response 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 needs to sit on the outside surface of a small-bore pipe, tube, nozzle, or compact cylindrical component and support circumferential weld inspection or circumferential OD scanning.

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

Typical Applications

·       PAUT weld inspection on circumferential OD curved surfaces

·       Small-bore pipe circumferential weld inspection

·       Tube and compact cylindrical component inspection

·       Nozzle weld inspection where COD geometry is required

·       Pipe spool weld inspection on outside-diameter curved surfaces

·       Process piping weld inspection

·       Compact pressure component inspection

·       Restricted-access PAUT weld inspection

·       Fabrication and site-based weld inspection

·       Refinery, petrochemical, and power plant inspection applications

·       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 COD Wedge is suitable for small-bore pipes, tubes, nozzles, compact cylindrical parts, pipe spools, process piping welds, and outside-diameter curved weld inspection zones. It is useful where the inspection surface requires OD curvature matching and the wedge orientation follows the circumferential profile of the component.

For flat surfaces, the Flat Wedge configuration is recommended. For axial OD inspection, AOD 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.
