Abstract [eng] The aim of this research was to find the most suitable ultrasonic non-destructive technique that would enable to find defects in dissimilar material joints made of steel and Glass Fiber Reinforced Polymer (GFRP). The selection of appropriate technique was performed by analysis of sample, ultrasound methods, types of transducers as well as ultrasonic wave propagation characteristic, paths, amplitude value of peaks. Firstly the sample was designed in CIVA software where different solutions were used to compare the results of investigations. It was determined that inspection is most effective from metal side since the attenuation in steel is 3 time less than in GFRP. Pulse-echo technique and phased array transducers were selected as the most suitable configuration for inspection of the sample. By comparing amplitudes of signal reflected from the defect area and interface without defect it was determined that the difference is very low and it leads to the fact that it can be difficult to locate delaminations experimentally. To avoid this complication comparison of multiple reflections from defect and interface without defect was performed. In experimental part all delaminations as well as their dimensions were determined. As a result of this research, the best configuration for the delamination detection in dissimilar steel and GFRP sample was found.
