When metal structures are manufactured, the heat cycle introduced by the applied welding technology can cause structural changes in the base material, as well as residual stresses, which under certain circumstances can lead to changes in the shape of the structure. This paper analyses certain possibilities to avoid and reduce the stress level and the distortions in the welded structure by applying various welding technological methods. The paper presents the results obtained after the fillet welds were made using ...

The welding characteristics of the welded joints are directly influenced by the thermal conditions applied during welding. At the same time, the welding type process influences the geometry of the welded seam, the nature and the extent of the structural transformations, the tensions and deformations level, as well as the values of the mechanical characteristics of the welded bead (yield strength, hardness, toughness etc.) The paper presents the experimental procedure, the results and the conclusions on the influen...
