  • Page 57: Weld Inspection Using Trigonometry Mode

    The trigonometry mode provides a convenient method for measuring the location of discontinuities when inspecting welds with angle beam transducers. Essentially, the trigonometry mode uses the thickness gauging features of the Sitescan 150 to calculate the surface distance and depth to a discontinuity from the actual beam path measured. This is accomplished by calibrating the trig mode with the actual refracted angle of the transducer being used.

  • Page 70: Adjustment

    Sitescan 150 User’s Guide ~ Flaw Testing The calibration of the DGS/AVG system sets the Probes ‘absolute sensitivity’ based on the response from the reference block. Changing any parameters relating to the reference echo will invalidate the calibration, which must then be repeated. The current version of the software does not enforce this – it is the responsibility of the operator.
  • Page 71 Sitescan 150 User’s Guide ~Flaw Testing Gain may be adjusted with understanding – Changing the Gain setting will remove the correlation with the DGS/AVG curve, so should only be done in accordance with a specification , for example to compensate for varying material conditions (better done with the T-LOSS function).
