The AWS Wedge 0.63" x 0.63", 70 degrees (W-106 70°) is a specifically designed acrylic wedge used in conjunction with an AWS (American Welding Society) style angle beam ultrasonic transducer, particularly the AWS SGE0050 model or other compatible probes of similar dimensions and interface. This wedge serves as a critical component in angle beam ultrasonic testing, enabling the introduction of a refracted shear wave into the material under inspection at a nominal angle of 70 degrees.

Key Features:

• Probe Interface Dimensions: The wedge features a contact surface with the probe measuring 0.63 inches by 0.63 inches (approximately 16 mm x 16 mm), ensuring proper physical coupling with compatible transducers like the AWS SGE0050.

• Nominal Refracted Angle: Engineered to produce a refracted shear wave angle of 70 degrees within the test material (typically steel). This specific angle is commonly employed for detecting and characterizing weld defects and other discontinuities that are not optimally oriented for straight beam inspection.

• Designation (W-106 70°): The identifier "W-106 70°" likely represents a specific part number or industry designation that uniquely identifies this particular wedge type, size, and refracted angle.

• Material Composition: Typically manufactured from acrylic or another polymer material that exhibits good acoustic transmission properties at ultrasonic frequencies, facilitating efficient coupling of the sound energy into the test piece.

• Application Specificity: Designed to meet the requirements of ultrasonic testing performed in accordance with AWS standards and other relevant inspection codes that necessitate the use of 70-degree shear wave angle beam techniques.

Applications:

• Weld Inspection: Primarily used for the ultrasonic inspection of welds to detect various types of discontinuities such as cracks, lack of fusion, and porosity. The 70-degree shear wave angle is particularly effective for detecting transverse flaws in welds.

• General Angle Beam Testing: Can be employed in other ultrasonic testing scenarios where a 70-degree refracted shear wave angle is required for flaw detection and characterization in different materials and geometries.

Importance:

• Enables Angle Beam Inspection: Facilitates the introduction of a refracted sound beam at a specific angle into the test material, allowing for the detection of flaws that may not be readily detectable with straight beam techniques.

• Optimized for Weld Inspection: The 70-degree shear wave angle is a standard and effective angle for many weld inspection applications as defined by AWS and other codes.

• Ensures Proper Coupling: The specific dimensions are designed for optimal acoustic coupling with compatible AWS style probes, maximizing the transmission of ultrasonic energy.
