Ultrasonic Flaw Detector Calibration and Repair Services
• Calibration is a crucial process for non-destructive testing professionals to ensure the accuracy and precision of their ultrasonic flaw detector.• It involves setting the measuring instrument with a standard unchanging reference material that meets certain specifications.
• The process often occurs in two stages: manufacturer calibration and user calibration.
• Calibration is essential to reduce the cumulative margin of error and ensure the detector is accurate and error-free.
• Three calibration processes are required: zero offset calibration, material velocity calibration, and auto calibration.
• Calibration certification documents the detector's linearity and measurement accuracy under specific test conditions.
• To calibrate an ultrasonic flaw detector, three steps are used: setting the probe in position A with the right coupling, adjusting the range and sound velocity, and setting the angle probe for angle.
