Phoenix produces a wide range of Time of Flight Diffraction wedges manufactured from durable plastic, brass or stainless steel. The wedges fit the universal Metric Threaded probes (M12, M20 and M30) and are suitable for use with the Phoenix range of TOFD probes.

  • All TOFD wedges are supplied with M3 irrigation channels as standard
Technical Specification
  • Sound Velocity: 2320m/s.
  • Beam angles specified are for longitudinal waves.
  • Nozzle fits a 2.5-3mm tube.
  • Gimbal centre is 7.00mm from wedge base.
  • Gimbal is 5mm Ø x 3.85mm long (hex 3mm key).
  • All wedges are irrigated as standard and can be coupled with couplant gel or water as required.
Accessories
  • Wear Plates or Couplant Skids must be ordered with the wedge as the addition of M3 x 5 deep hole is required. Wear plates are available for the front and rear of the wedge.
  • Side Skids are available but incompatible with tool-post applications.
Usage

Couplant must be applied to the probe face and the wedge shoe during use (this can be pumped or applied manually). Phoenix Inspection Systems Limited assumes no responsibility, explicit or implicit, if these results are found to vary under different test conditions.
