Miniature Angle Beam Transducers and Wedges are used primarily for testing of weld integrity. Their design allows them to be easily scanned back and forth and provides a short approach distance.
Angle beam transducers are single element transducers used with a wedge to introduce a refracted shear wave or longitudinal wave into a test piece.
Advantages:
- Three-material design of our Accupath wedges improves signal-to-noise characteristics while providing excellent wear resistance
- High temperature wedges available for in-service inspection of hot materials
- Wedges can be customized to create nonstandard refracted angles
- Available in interchangeable or integral designs
- Contouring available
- Wedges and integral designs are available with standard refracted angles in aluminum
Applications:
- Flaw detection and sizing
- For time-of-flight diffraction transducers see page 25
- Inspection of pipes, tubes, forgings, castings, as well as machined and structural components for weld defects or cracks
Miniature Screw-In Transducers
- Screw-in design 303 stainless steel case
- Transducers are color coded by frequency
- Compatible with Short Approach, Accupath, High Temperature and Surface Wave Wedges
