Additive technologies are becoming increasingly important in the industry because they enable the production of complex geometries with minimal waste. This master's thesis explores the impact of MIG welding parameters on the properties of 3D-weld cladded walls made from aluminum alloy 7075, which is crucial in the aerospace industry due to its excellent strength-to-weight ratio. The research involved creating various samples with different parameter variations. In the research, different methods, such as XRD residual stress analysis, EDS analysis, microhardness measurements, metallographic analysis, and tensile tests, were used to analyze the material and mechanical properties. The findings indicate that vibrations during welding reduce residual stresses but increase porosity. Higher porosity levels lead to lower tensile strength and microhardness. Microchemical EDS analysis confirmed the presence of various intermetallic phases, including S-phase, θ-phase, T-phase, and η-phase.
