An ultrasonic crack tip diffraction technique is one of the technique used in detection of buried defect in welded steel. To obtain the desired condition with regarded to welded steel maintenance, a research project has been initiated. The objective of this project is to develop a fast and reliable ultrasonic crack tip diffraction technique for detection size and depth of buried defect in steel. Time of flight diffraction method and crack tip diffraction technique are both using time of flight measurement of the diffracted signal from the crack tip, are empioyed. For this experiment, 56.77mm of probe distance, 7.20mm of probe diameter were used. Calibration block, which have notch at 50%of through depth for correct calibration was used. A relationship between measured value of steel can be observed by using the amplitude shown on the screen. It shown, the actual value and measured value depth of defect in steel does not have any significant discrepancy |
