Calibrating the Instrument and Measuring Prior to carrying out any inspection task, it is necessary that the instrument be calibrated for sound velocity, pitch interval and probe delay, according to the test piece and to conform with the test specifications which might apply to the test application.
  • Page 132 4.1.2 Calibrating with unknown MTLVEL Operating procedure: 32． First enter an estimated sound velocity value. 33． Select Double Gate mode by adjusting the gate logic. 34． Couple the probe to a calibration test block of a known thickness and whose material is similar to that of the test piece.
  • Page 133 48． Adjust the gate heights, so that they are at the same positions of the front edges of two standard echoes. 49． Adjust the sound velocity, until it displays the thickness value of the standard test block. 50． Set the Gate Logic to Single-Gate mode, i.e. Positive or Negative logic. The pitch interval measured at this point is the pitch interval of the primary echo.
  • Page 134 sound velocity. 4. Calibration of the probe zero point. Repeat the procedure above, and change the gate mode to plus or minus. Adjust the probe zero point to make the value of the sound path (S) return to 100. The zero point value obtained is the actual zero point value.
  • Page 135 adjust the gain so that the echo crosses the A-Gate and the highest peak in gate A is at approximately 80% of full-screen height. The highest peak must not be higher than 100%full-screen height. And then turn around the fast rotary knob to record the second DAC curve point. When the value of the RECCORD function changes from 1 to 2, you have recorded the second DAC curve point.

Factors Influencing the Inspection Accuracy and the Evaluation of Defects Before operating the UFDX5, please read the following technical information, paying particular attention to important instructions that are given regarding the operation of the instrument. This is very important in order to avoid possible errors occurring when operating the instrument, which may result in invalid test results.
  • Page 141 6.1.3 Testing range It is important to understand that the echo, which is displayed on the screen, only represents part of the actual acoustic beam spread of the probe through the test piece. Operators should therefore be careful when comparing and interpreting the displayed information received from the area of the part under test, to the untested areas.
  • Page 142 will influence the measuring accuracy. 6.1.5 Measuring the remaining Wall Thickness of test pieces When measuring the remaining wall thickness of test pieces (e.g. pipes, containers and various reaction vessels whose internal surfaces might be corroded or eroded), an ultrasonic thickness gauge should be used, paying attention to the selection of the correct probe and inspection procedure.
  • Page 143 material (e.g. non-ferrous metals or plastics), the sound velocity could vary drastically through the test piece, therefore it will influence the measuring accuracy. If the material of the test piece being inspected is not isotropic, the sound velocity will vary as the operator scans in different directions.
  • Page 144 detecting the edge of the defect and determining its range. b. If the diameter of the acoustic beam is greater than the length of the defect, a comparison must be made between the maximum echo response of the defect, and the maximum echo response of an artificial defect. 6.3.1 Defect edging method The smaller the acoustic beam diameter of the probe is, the more accurate the edge definition is, and therefore the defect length can be determined more accurately.
