Angle Beam

Angle Beam Transducers

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
