Sonatest — X2AW-0L25 Ultrasonic Wedge

0° Straight-Beam X2 Wedge, 25 mm Thick, with Irrigation and Radius / Contouring
SKU: X2AW-006

Overview

The Sonatest X2AW-0L25 is a 0-degree ultrasonic wedge designed for use with compatible X2-series ultrasonic transducers. It features a nominal 25 mm thickness, a straight-beam configuration, and provisions for irrigation and radius / contouring, making it suitable for ultrasonic inspection of curved or cylindrical components where consistent coupling and stable probe contact are important.

The 0° configuration directs ultrasonic energy approximately perpendicular to the inspection surface, supporting normal-incidence pulse-echo inspection. This makes the wedge suitable for applications such as material evaluation, back-wall monitoring, lamination detection, thickness-related inspection, and internal reflector evaluation.

The integrated irrigation capability can assist with maintaining a consistent supply of ultrasonic couplant during scanning, while the radius / contouring configuration allows the wedge contact surface to be adapted to curved test pieces when required.

SKU X2AW-006 is suitable for professional ultrasonic testing in fabrication, manufacturing, maintenance, piping inspection, structural evaluation, and industrial QA/QC environments.

Key Specifications

Inspection Configuration

Actual ultrasonic performance depends on transducer frequency, component material, contour radius, couplant, wedge condition, and instrument setup.

Performance Features

0° Straight-Beam Configuration
Introduces ultrasonic energy approximately normal to the inspection surface for conventional straight-beam testing.

25 mm Wedge Thickness
Provides a defined acoustic path between the transducer and inspected component.

Integrated Irrigation Capability
Allows couplant to be supplied to the inspection interface during scanning, helping maintain consistent acoustic coupling.

Radius / Contouring Capability
Supports adaptation of the wedge contact surface to curved or cylindrical components for improved physical contact.

Designed for X2-Series Transducers
Configured for use with compatible Sonatest X2 ultrasonic probes.

Reusable Inspection Accessory
Can be used repeatedly when properly maintained and when the contoured contact surface remains within calibration requirements.

Irrigation Advantages

The irrigation provision can provide several benefits during manual or controlled scanning:

• Helps maintain a continuous couplant film

• Reduces interruptions for manual couplant application

• Supports more consistent acoustic transmission

• Can improve scanning efficiency

• Useful for repetitive inspections

• Helps maintain coupling on curved surfaces

• Supports extended scan lengths

• Can be integrated with suitable couplant-delivery systems

Flow rate, couplant type, and delivery equipment should be selected according to the inspection procedure.

Radius / Contouring Advantages

A contoured wedge surface can improve inspection performance on curved components.

Potential benefits include:

• Improved contact on cylindrical surfaces

• Reduced wedge rocking

• More stable probe positioning

• More consistent coupling

• Better repeatability during scanning

• Improved ultrasonic energy transfer

• Easier inspection of piping and curved components

• Reduced couplant gaps between the wedge and test surface

The contour radius should closely match the actual component radius for optimum contact.

Typical Components Inspected

The X2AW-0L25 may be suitable for:

• Process piping

• Cylindrical vessels

• Pressure vessels

• Storage tanks

• Curved structural components

• Steel plate

• Forgings

• Castings

• Machined parts

Typical Inspection Targets

When used with a compatible X2 transducer and properly calibrated ultrasonic instrument, the wedge can support evaluation of:

• Back-wall reflections

• Laminations

• Internal inclusions

• Thickness variations

• Material loss

• Internal reflectors

• Certain volumetric discontinuities

• Other reflectors favorably oriented to a normal-incidence sound beam

Detectability depends on discontinuity orientation, size, depth, material properties, transducer frequency, surface geometry, and calibration.

Inspection Guidelines

• Confirm compatibility between the X2 transducer and wedge

• Verify that the wedge contour matches the component radius

• Inspect the contact surface for wear or damage

• Mount the transducer securely

• Connect the irrigation system when required

• Verify couplant flow before scanning

• Apply suitable ultrasonic couplant

• Calibrate zero, range, sound velocity, and sensitivity

• Position the wedge firmly against the curved or flat surface

• Maintain consistent orientation during scanning

• Monitor coupling and irrigation flow

• Record relevant indications and measurement locations

• Recheck calibration periodically

Contouring and Calibration

Contouring modifies the contact geometry of the wedge and can affect the acoustic path.

Whenever the wedge is contoured:

• Confirm the required component radius

• Maintain a smooth and uniform contact surface

• Avoid excessive material removal

• Verify wedge thickness after contouring

• Recalibrate the ultrasonic system

• Check zero offset

• Confirm sound-path behavior

• Verify probe stability on the component

• Replace the wedge if excessive wear changes the intended contour

Unauthorized or uncontrolled modification of the wedge may affect inspection accuracy.

Irrigation System Considerations

For irrigation-assisted inspection:

• Use couplant compatible with the wedge and inspected component

• Maintain a controlled flow rate

• Avoid excessive flow that interferes with probe handling

• Keep irrigation passages clear

• Flush the system after use when necessary

• Prevent dried couplant from blocking fittings or channels

• Inspect tubing and connections before inspection

• Follow applicable equipment-cleaning procedures

Care and Handling

• Avoid dropping or striking the wedge

• Keep all coupling surfaces clean

• Remove couplant after inspection

• Flush irrigation passages when required

• Inspect the contoured contact surface regularly

• Protect the wedge face from scratches

• Avoid unauthorized grinding or reshaping

• Store in a clean, dry location

• Keep protected during transportation

• Replace the wedge if wear affects coupling, contour fit, calibration, or sound transmission
