Sažetak
Nowadays, heterogeneous welded joints in metallic constructions are more and more frequently used so that these welded joints are the subject of a large number of investigations. In the present paper, welded joints consisting of micro alloy steel and austenitic steel realized with various filler metals and welding technologies are presented. The conducted testing was aimed at establishing the effect of the type of filler metal and heat input on the total impact energy, crack-initiation and crack-propagation energy as well as on the fracture toughness at plane-strain state of ferritic-austenitic welded joints. Optimum welding technology providing the highest welded-joint safety and extending operation life of construction has been defined.
