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
