Targeted Angle Beam Inspection: CT QUICK CHANGE WEDGE (1/4", 70°, R2") "70°, RADIUS 2" ONLY"

Optimize your ultrasonic testing (UT) capabilities for angle beam inspections with the CT QUICK CHANGE WEDGE, specifically designed for use with 1/4" diameter transducers, featuring a 70° refracted angle, and a 2" radius for curved surfaces. From CT, a provider of reliable NDT accessories, this wedge is an essential component for introducing highly acute shear waves into materials, enabling the precise detection and sizing of flaws that are often difficult to find with shallower angles.

Key Features and Benefits:

• Quick Change / Interchangeable Design: The "Quick Change" feature allows for rapid and easy swapping of transducers or wedges without the need for tools. This significantly boosts efficiency during inspections that require changes in probe size, angle, or surface contour adaptation.

• Optimal 1/4" Transducer Compatibility: Designed to perfectly couple with 1/4-inch diameter ultrasonic transducers. This common transducer size offers a good balance of beam spread and resolution, suitable for a wide range of flaw detection applications.

• Precision 70° Refracted Angle: This wedge produces a 70-degree refracted shear wave in common materials like steel. This highly acute angle is particularly effective for detecting near-surface flaws (such as hydrogen-induced cracking, intergranular stress corrosion cracking, or laminations that break the surface) and for inspecting thinner sections where the sound path is short. It's also valuable for examining the weld cap and fusion line areas.

• Contoured for 2" Radius Surfaces: Features a precisely machined bottom surface with a 2-inch radius. This contour ensures optimal acoustic coupling and consistent sound entry when inspecting curved surfaces, such as:

  • Smaller diameter pipes (e.g., 4" diameter and larger)

  • Smaller radius pressure vessel components

  • Other components with a similar convex or concave geometry. This intimate contact maximizes signal strength and accuracy.

• Durable Construction: Manufactured from high-quality, wear-resistant material (e.g., acrylic or polyimide, depending on temperature requirements). This robust construction ensures long life and stable acoustic properties, even with repeated use in demanding industrial environments.

• Consistent Acoustic Coupling: The flat top surface ensures stable and repeatable coupling with the transducer, while the contoured bottom surface provides excellent contact with curved parts, minimizing signal loss due to poor coupling.

• Essential for Critical Weld & Crack Detection: Angle beam wedges are critical for:

  • Weld Inspection: Especially effective for detecting defects at or very near the weld cap, root, and fusion line, and for thin-wall welds.

  • Near-Surface Crack Detection: Highly sensitive to cracks and other discontinuities that are oriented perpendicular to the surface or very close to it.

  • Shear Wave Applications: Introducing shear waves for material characterization and flaw sizing.

Equip your ultrasonic testing toolkit with the CT QUICK CHANGE WEDGE (1/4", 70°, R2") to enhance your ability to perform accurate, reliable, and efficient angle beam inspections on both flat and curved surfaces, particularly when a very steep inspection angle and near-surface sensitivity are required.
