NM01QW5070D

This Dakota Ultrasonics 70-degree angle beam wedge is a precision-crafted accessory designed for seamless integration with their Quick Change (QC) series ultrasonic transducers featuring a 1/2 inch diameter. This wedge is specifically engineered to facilitate advanced angled beam ultrasonic testing, a crucial methodology for the detailed examination of materials and the detection of subsurface imperfections, particularly those with orientations that might be challenging to identify with shallower angle beams.

The primary function of this wedge is to accurately refract the ultrasonic beam emitted by a compatible QC transducer at a steep 70-degree angle as it enters the material under inspection (typically calibrated for steel; the actual refracted angle may exhibit minor variations depending on the acoustic velocity of the specific material being evaluated). This steeper 70-degree angle is a valuable tool in ultrasonic non-destructive testing, especially in the critical examination of welds, where it is highly effective in detecting specific types of defects, including certain vertically oriented cracks, lack of sidewall fusion in specific weld joint configurations, and other anomalies that present a steeper reflective surface to the sound beam.

Engineered for optimal compatibility with Dakota Ultrasonics' Quick Change (QC) probe system, this wedge incorporates a specialized interface that enables rapid, secure, and tool-free attachment and detachment of 1/2 inch diameter QC transducers. This intelligent quick-change mechanism significantly enhances the efficiency of inspections, allowing technicians to swiftly adapt to different testing requirements and beam angles without the need for time-consuming adjustments or specialized tools.

Manufactured by Dakota Ultrasonics, a recognized and respected leader in the field of non-destructive testing (NDT) equipment, this 70-degree wedge is constructed to ensure consistent and reliable acoustic coupling between the transducer and the test surface. When used in conjunction with an appropriate ultrasonic couplant, it facilitates the efficient transmission of ultrasonic energy at the intended 70-degree angle, providing accurate and dependable results for specialized angled beam inspection applications. This wedge is an essential component for NDT professionals utilizing Dakota Ultrasonics' QC probe system for comprehensive and nuanced material evaluation, particularly when investigating potential flaws with steeper orientations within the test piece.
