Wedge (Angle Beam)
A plastic or composite plastic device placed between an angle-beam transducer and test surface to tilt the transducer at a specific angle. Wedges are designed with specific angles (typically 45°, 60°, or 70°) to generate shear waves at desired angles within the material. Wedge quality and coupling are critical to achieving consistent angle-beam results. Standard wedge geometries ensure reproducibility across inspections.

Equipment Selection and Use
Proper selection and maintenance of wedge (angle beam) is critical for successful NDT inspections. Equipment must be calibrated and verified per applicable standards.
Maintenance and Verification
Regular maintenance and calibration verification ensure reliable equipment performance. Equipment that falls out of calibration can produce unreliable results.
Best Practices
- Always follow applicable NDT standards and procedures
- Use properly calibrated and maintained equipment
- Ensure personnel are properly trained and certified
- Document inspection procedures and results completely
- Keep current with industry standards and best practices
