The QUICK CHANGE WEDGE, identified with a nominal size of 1/2" and a refracted angle of 45 degrees, is a versatile ultrasonic testing (UT) accessory designed to streamline angle beam inspections. Featuring an efficient "Quick Change" mechanism, this wedge allows for rapid and tool-free interchange of compatible ultrasonic transducers. This capability is particularly beneficial in inspection settings where technicians need to switch between different transducers or inspection angles frequently, leading to significant time savings and improved workflow.  

The "1/2"" 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 slightly larger physical size compared to a 1/4" wedge, potentially accommodating a wider range of transducer sizes or offering a larger contact surface for enhanced coupling.

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, resulting from the mode conversion of the longitudinal wave emitted by the transducer as it travels through the wedge material. A 45-degree angle is a commonly utilized inspection angle in ultrasonic testing, providing effective detection of 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 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 attached to and detached from the wedge without the need for any tools. This feature simplifies the inspection process, minimizes the risk of transducer damage during changes, and allows technicians to adapt quickly to varying inspection requirements.

Key Features:

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

• Nominal Size: 1/2" interface dimension, indicating compatibility with a range of 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.

• Increased Efficiency: Reduces time spent on transducer changes during inspections.  

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

• Essential for Angle Beam UT: Facilitates effective subsurface flaw detection at a 45-degree angle.

Applications:

• Ultrasonic inspection scenarios requiring frequent transducer or angle changes.

• Angle beam inspection of welds and other materials.

• General flaw detection in materials where a 45-degree refracted shear wave is advantageous.

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