The QUICK CHANGE WEDGE, identified with a nominal size of 3/8" and a refracted angle of 70 degrees, is a specialized ultrasonic testing (UT) accessory designed to enhance the efficiency of angle beam inspections. This wedge incorporates a "Quick Change" mechanism, enabling users to rapidly attach and detach compatible ultrasonic transducers without the need for tools. This feature is particularly valuable in inspection environments where frequent changes in transducers or scanning angles are necessary, leading to significant time savings and improved operational flow.

The "3/8"" 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 indicates a physical size that falls between the 1/4" and 1/2" versions, potentially offering a balance of transducer compatibility and coupling surface area.

The primary function of this wedge is to introduce a refracted ultrasonic beam into the test material at a 70-degree angle. This refracted angle is typically a shear wave, generated by the conversion of the longitudinal wave emitted by the transducer as it propagates through the wedge material. A 70-degree angle is a commonly utilized inspection angle in ultrasonic testing, particularly for detecting flaws that are oriented more perpendicular to the inspection surface or for specific weld geometries.

The "CT" designation indicates the manufacturer or supplier of this quick change wedge. As previously mentioned, "CT" could represent 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 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 and secure locking or clamping system that allows a transducer to be easily mounted to and released from the wedge without requiring any tools. This streamlined process minimizes downtime during inspections, reduces the potential for transducer damage during changes, and allows technicians to adapt quickly to varying inspection requirements.

Key Features:

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

• Nominal Size: 3/8" interface dimension, indicating compatibility with a range of transducer sizes.

• Refracted Angle: Produces a 70-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 time spent on transducer changes during inspections.  

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

• Essential for Angle Beam UT: Enables effective subsurface flaw detection at a 70-degree angle.

Applications:

• Ultrasonic inspection scenarios requiring frequent transducer or angle changes.

• Angle beam inspection of welds and other materials, particularly for detecting vertically oriented flaws.

• General flaw detection in materials where a 70-degree refracted shear wave is advantageous.

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