The Dakota NDT Snail Shear Wave Wedge, Model SNW6260, is a high-quality angle beam wedge meticulously engineered for use with compatible ultrasonic transducers in shear wave testing applications. This "snail"-style wedge features a contact surface of 0.625 inches by 0.625 inches (5/8" x 5/8") and is precisely angled to introduce a 60-degree refracted shear wave into the material under inspection.  

Snail wedges, a common and reliable design often referenced in industry standards, are widely used in critical weld examinations and other applications where a specific angle of incidence is crucial for effective flaw detection and accurate characterization. The 60-degree angle provides a valuable perspective for identifying various types of weld discontinuities and material defects, often complementing inspections performed with 45-degree wedges. This wedge is constructed to deliver consistent and dependable performance when paired with appropriate shear wave transducers, ensuring reliable inspection outcomes.
