NM01QAW6260

This designation describes a specific transducer wedge manufactured by Dakota NDT. It belongs to their Quick Change AWS Prove Up Wedge (QAW) series, designed for use with compatible quick-change ultrasonic transducers in non-destructive testing (NDT) applications.

Here's a breakdown of the information:

• WEDGES QAW: Indicates it's part of Dakota Ultrasonics' line of Quick Change AWS Prove Up Wedges. These are often used for weld inspection and to meet requirements of the American Welding Society (AWS). The "Quick Change" feature allows for fast and easy swapping of transducers.

• 6245: This part number, in conjunction with the "QAW" series, further specifies the wedge type. Based on Dakota's nomenclature, the "62" likely refers to the element size (0.625" x 0.625"), and while "45" often indicates a 45-degree angle in other Dakota part numbers, in the "QAW" series, the angle is explicitly stated separately.

• Element size 0.625" x 0.625": This confirms the dimensions of the contact face of the wedge that couples with the transducer. It measures five-eighths of an inch by five-eighths of an inch.

• 60 DEGREE: This is the crucial angle of the wedge. This angle determines the refracted angle of the ultrasonic beam (typically a shear wave) within the material being inspected. A 60-degree wedge is a common choice for various weld inspection techniques and other angled beam testing.

• DAKOTA: Clearly identifies the manufacturer as Dakota Ultrasonics, a reputable company in the field of ultrasonic testing equipment and accessories.

In summary, this is a Dakota Ultrasonics QAW series wedge with a 0.625" x 0.625" contact area and a 60-degree angle. It is designed for quick connection to compatible transducers and is likely intended for weld inspection and other NDT applications where a 60-degree refracted angle is required, possibly in accordance with AWS standards.
