Study of the effect shielding gas on the quality of weld and parameters of laser welding
Procházka, Libor ; Chudík, Ivan (referee) ; Mrňa, Libor (advisor)
The subject of this diploma thesis is the use of laser welding technology in protective atmospheres. Based on the literary research presented in the theoretical part of the thesis, two experiments were made. Welding of materials X5CrNi18-10 and X2CrNiMo17-13-2. Welded sheets were performed in three different protective atmospheres. Samples were made from the welded sheets for measuring tensile strength, hardness, macrostructure and microstructure. These samples were analyzed. The output of the analysis is the evaluation of the impact that the protective atmosphere have on the quality of the welded joint and optimal process parameters.
