20.500.12556/DKUM-94282 Vpliv varjenja na mehanske lastnosti jekla SA 500 magistrsko delo Influence of welding on the mechanical properties of steel SA 500 Magistrsko delo obravnava vpliv varjenja na mehanske lastnosti jekla SA 500 z dodajnim materialom EZ - MIG 307 Si. Uporabljen osnovni material spada med protibalistična jekla, ki imajo dobre mehanske lastnosti, zlasti trdnost in trdoto. Ker varjenje degradira osnovni material, bomo analizirali njegov vpliv na mehanske lastnosti. Izvedli smo natezni preskus, instrumentiran Charpyjev preskus in merjenje trdote po Vickersu. Z omenjenimi mehanskimi preskusi smo potrdili, da ima osnovni material visoko trdnost in trdoto, vendar je dokaj krhek. Z vnosom toplote (varjenjem) se ta krhkost odpravi in material postane bolj žilav, vendar se mu drastično zmanjšata trdnost in trdota. The master's thesis examines the impact of welding on the mechanical properties of SA 500 steel with the filler material EZ-MIG 307 Si. The base material used is among the anti-ballistic steels, which have good mechanical properties, especially strength and hardness. Because welding degrades the base material, we will analyze its impact on the mechanical properties. Tensile tests, instrumented Charpy tests and Vickers hardness measurements were performed. These mechanical tests confirmed that the base material has high strength and hardness but is quite brittle. The input of heat (welding) removes this brittleness and makes the material tougher, but drastically reduces its strength and hardness.
