The QUICK CHANGE WEDGE, identified with a nominal size of 1/4" and a refracted angle of 60 degrees, is a specialized ultrasonic testing (UT) accessory designed for efficient angle beam inspections. This wedge features a "Quick Change" mechanism, allowing for swift and tool-free attachment and detachment of compatible ultrasonic transducers. This design is particularly advantageous in inspection environments where multiple transducers or scanning angles are frequently employed, significantly reducing setup time and enhancing overall productivity.

The "1/4"" designation likely refers to a key interface dimension of the wedge, such as its thickness at a specific point or the size of the transducer contact area. This dimension provides a general indication of the physical size of the wedge and the range of transducers with which it is intended to be used.

The primary function of this wedge is to introduce a refracted ultrasonic beam into the test material at a 60-degree angle. This refracted angle is typically a shear wave, generated through the mode conversion of the longitudinal wave emitted by the transducer as it propagates through the wedge material. A 60-degree angle is a widely used inspection angle in ultrasonic weld testing and general flaw detection, offering a good balance of sensitivity for various flaw orientations and penetration depth.

The "CT" designation indicates the manufacturer or supplier of this quick change wedge. As previously noted, "CT" could represent Curtis Testing, a recognized provider of non-destructive testing (NDT) equipment and accessories, or another reputable company with these initials. The specific design and operation of the quick change mechanism, as well as the material composition and acoustic properties of the wedge, will be determined by this manufacturer.

The quick change functionality typically involves an intuitive locking or clamping system that enables a transducer to be securely mounted to the wedge and easily released without the need for any tools. This feature streamlines the inspection process, reduces the potential for transducer damage during changes, and allows technicians to adapt quickly to different inspection requirements.

Key Features:

• Quick Change Mechanism: Facilitates rapid, tool-free attachment and detachment of compatible transducers.

• Nominal Size: 1/4" interface dimension, indicating compatibility with certain transducer sizes.

• Refracted Angle: Produces a 60-degree refracted shear wave in the test material (typically steel).

• Manufacturer: Identified as "CT," potentially Curtis Testing or another company with these initials.

• Improved Efficiency: Reduces downtime associated with transducer changes.

• Secure Transducer Coupling: Ensures optimal transmission of ultrasonic energy.

• Essential for Angle Beam UT: Enables effective subsurface flaw detection at a 60-degree angle.

Applications:

• Ultrasonic inspection scenarios requiring frequent transducer or angle changes.

• Angle beam inspection of welds in accordance with various standards and procedures.

• General flaw detection in materials where a 60-degree refracted shear wave is advantageous.

• Use with compatible ultrasonic transducers designed for wedge coupling and the quick change mechanism.
