Mô tả

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
