The Dakota NDT Snail Shear Wave Wedge, Model SNW6270, 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 70-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 70-degree angle provides a unique and valuable perspective for identifying specific types of weld discontinuities and material defects, often complementing inspections performed at other angles for comprehensive coverage. This wedge is constructed to deliver consistent and dependable performance when paired with appropriate shear wave transducers, ensuring reliable inspection outcomes.
