The Dakota NDT Standard Angle Beam Wedge (SW) is a crucial accessory designed for use with shear wave transducers featuring a 0.750” x 0.750” (3/4" x 3/4") element. This specific wedge provides a 45-degree refracted shear wave angle within the test material (the exact angle may vary slightly depending on the acoustic properties of the material under inspection, typically calibrated for steel).  

These wedges are indispensable for performing angle beam ultrasonic testing, enabling the transducer to introduce a sound wave at a specific, controlled angle into the material being examined. This technique is vital for detecting flaws that are not oriented perpendicular to the surface, a common occurrence in weld inspections and other critical applications. Constructed from durable materials with optimized acoustic properties, these 45-degree angle beam wedges ensure efficient and reliable transmission of the ultrasonic signal into the test piece, leading to accurate and dependable inspection results.  

Key Selling Points:

• Optimized for 0.750” x 0.750” Transducers: Ensures proper acoustic coupling and optimal beam introduction from transducers of this size.  

• Provides a Versatile 45-Degree Refracted Angle: A widely used and effective angle for shear wave inspection, particularly beneficial for many weld inspection scenarios and general flaw detection.  

• Essential for Angle Beam UT: Enables the detection of flaws oriented at various angles relative to the inspection surface, expanding inspection capabilities.  

• Durable Construction for Reliable Use: Built to withstand the demands of typical inspection environments, ensuring long-lasting performance and consistent results.  

• Ensures Efficient Ultrasonic Transmission: Optimizes the entry of the ultrasonic wave into the test material, maximizing signal quality and detection sensitivity.  

Benefits:

• Effective Detection of Angled Flaws: Specifically designed to aid in the identification of discontinuities that are not perpendicular to the surface, a common challenge in many inspection tasks.

• Versatile for a Wide Range of Applications: The 45-degree angle is commonly employed in weld inspection, general flaw detection, and the inspection of various components and materials.

• Ensures Reliable Acoustic Coupling: Designed to provide a secure and effective interface with compatible transducers, maximizing signal transfer.  

Approximate Dimensions (inches):

• Transducer Interface Area: 0.750 inches x 0.750 inches (designed to perfectly match a 3/4" x 3/4" transducer face).

• Wedge Length: Approximately 1.0 to 1.5 inches (This dimension can vary slightly depending on the specific design and the 45-degree angle).

• Wedge Width: Approximately 0.75 inches (to align with the transducer interface).

• Wedge Height (maximum): Approximately 0.5 to 1.0 inches (This dimension is influenced by the 45-degree angle and the transducer interface).

Applications:

These 45-degree standard angle beam wedges are commonly used in conjunction with compatible 0.750” x 0.750” shear wave transducers for a wide array of ultrasonic testing applications, including:

• Comprehensive weld inspection to detect critical defects such as lack of fusion, cracks, and porosity.  

• General flaw detection in various materials, identifying angled cracks, inclusions, and other discontinuities.  

• Inspection of pipes, pressure vessels, and storage tanks to examine welds and base materials for potential flaws.

• Quality control processes in manufacturing and fabrication to ensure the structural integrity of materials and components.
