| Abstract [eng] |
On the present work the quality of joint of dissimilar materials was inspected using ultrasonic waves. Various ultrasonic techniques and sample characteristics were analyzed to develop suitable configuration for the inspection of joint of dissimilar materials. Using CIVA software the sample was designed and virtual ultrasonic inspections performed using conventional, focused and phased array transducers with a frequency range from 3,5 MHz to 10 MHz. Suitable type and frequencies of ultrasonic transducer as well as the side of the sample from which the inspection has to be performed are selected according to results of CIVA modelling. Using Omniscan measurement system and phased array transducers of 3,5 MHz and 5 MHz the delaminations between dissimilar joints were found experimentally. The lengths of delaminations and their depths were measured and compared to theoretically calculated values. Using Tecscan measurement system and immersion transducers the location of defects was determined. The uncertainties of results of ultrasonic testing were estimated. . |
