AB  - Selection of steel, dimensions and fabrication technology for the welded structure are all parts of the design
process, because they are in close connection with the function of the structural whole under certain conditions of
exploitation for the predicted service life. Quality of welded joints in the process of production of the welded structure is
being defined by properties that the structure has to possess in order to fulfill certain requirements, which is being
accomplished by the selection of the adequate welding procedure and welding parameters, implementation of inspection
programs for all technological operations, as well as by performing mechanical and technological tests in order to
determine the magnitude of strength and deformation of base material and welded joints. Constituent parts of a welded
joint are base material, heat affected zone and weld metal. Heat affected zone of structural steels is being characterized by
the fusion zone, overheating zone, zone of complete normalization and zone of incomplete normalization.
In this paper the effect of change in hardness of weld metal and heat-affected zone on mechanical properties of
welded joints when base material is quenched and tempered steel C45 is being considered. Test results showed that the
application of welded structures made of quenched and tempered steels with hardness HV10 > 400 and tensile strength
UTS > 600 MPa is useful only when the stress concentration is low (αs ≤ 2) and when there are no residual stresses due to
welding.
