The primary aim of the study was to determine impact strength of dissimilar welded joints in the weld as well as the heat-affected zone (HAZ) and to determine the relationship of impact strength with microstructure and phase composition. Microfraction graphic analyses were conducted using scanning electron microscopy (SEM). In order to identify the phase composition and the physico-chemical state of phases X-ray diffraction analyses were conducted. Steel of ferritic structure grade X2CrNi12 and steel of austenitic structure grade X5CrNi 18-10 were used in the analyses. GMA welding was performed with the use of three different filler metals. Impact strength testing was performed at a temperature of -20 °C.
