In this thesis, we investigated the influence of laser shock peening without coating (LSPwC) on aluminum alloys manufactured using wire arc additive manufacturing (WAAM). The study focused on the analysis of residual stresses and surface topography in specimens treated with various combinations of LSPwC parameters (power density and overlap rate). Additionally, we examined the effect of inter-process vibrations introduced during the WAAM process and evaluated their impact on the final surface topography and residual stress state. Residual stresses were measured using X-ray diffraction (XRD), while surface topography was evaluated via digital microscopy. The results showed that an appropriate combination of LSPwC processing parameters and the application of inter-process vibrations during WAAM can significantly improve the residual stress state and reduce surface waviness.
