The paper presents the results of non-destructive and destructive tests od dissimilar high-strength low-alloy S460ML and S460N butt joints. These steels are characterized by similar mechanical properties, but their carbon equivalent CeIIW is much different. The joints were made using different values of heat input for each welding bead. They were tested by non-destructive methods: visual, penetrant, radiographic and ultrasonic tests. Then, the destructive tests were made: static tensile test, bending test, impact test and Vickers HV10 hardness measurements. The results of prepared examinations showed, that welding with higher heat input has significant impact on the mechanical properties of the dissimilar steel joints – the joint welded with bigger heat input was characterized by better mechanical properties.
