Abstract
This paper deals with the results of research conducted on quenched and tempered microalloyed steel. The welding process applied the MAG procedure with various heat inputs. In order to relieve the residual stresses, the annealing was done at 450, 550 and 650°C. The influence of heat input and stress relieving heat treatment has been researched by testing mechanical properties.
