The QUICK CHANGE WEDGE, identified with a nominal size of 1/4" and a refracted angle of 45 degrees, is a specialized ultrasonic testing (UT) accessory designed for angle beam inspections. A key feature of this wedge is its "Quick Change" mechanism, which allows for rapid, tool-free mounting and removal of compatible ultrasonic transducers. This innovative design significantly enhances inspection efficiency, particularly in scenarios where frequent transducer changes are required to accommodate different inspection angles, frequencies, or flaw detection strategies.  

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

The primary function of this wedge is to introduce a refracted ultrasonic beam into the test material at a 45-degree angle. This refracted angle is typically a shear wave, generated by the conversion of the longitudinal wave emitted by the transducer as it passes through the wedge material. A 45-degree angle is a commonly employed inspection angle in ultrasonic testing, offering good sensitivity for detecting various flaw orientations within the material, especially those oriented at or near this angle relative to the inspection surface.  

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

The quick change functionality typically involves a secure locking or clamping mechanism that allows a transducer to be easily attached and detached from the wedge without the need for tools like screwdrivers or wrenches. This feature saves valuable time during inspections and reduces the risk of damage to transducers during changes.

Key Features:

• Quick Change Mechanism: Enables rapid, tool-free transducer mounting and removal.

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

• Refracted Angle: Produces a 45-degree refracted shear wave in the test material (typically steel).

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

• Enhanced Efficiency: Speeds up inspections requiring multiple transducer or angle changes.

• Secure Transducer Mounting: Ensures reliable coupling between the transducer and the wedge.

• Essential for Angle Beam UT: Facilitates the introduction of angled sound beams for subsurface flaw detection.

Applications:

• Ultrasonic inspection scenarios requiring frequent transducer changes.

• Angle beam inspection of welds and other materials.

• Applications where a 45-degree refracted shear wave is the preferred inspection angle.

• Use with compatible ultrasonic transducers designed for wedge coupling.
