Abstract

Cilj ovog diplomskog rada bio je istražiti i optimizirati parametre ručnog laserskog zavarivanja aluminijskih legura, s posebnim fokusom na primjenu fiber lasera. U teorijskom dijelu analizirane su različite vrste lasera koji se koriste za zavarivanje tankostjenih materijala, te je detaljno proučen fiber laser zajedno s parametrima zavarivanja. Istražena je interakcija laserske zrake s osnovnim materijalom te su proučene preporuke norme HRN EN 1011-6:2018. U eksperimentalnom dijelu provedena su... More nerazorna i razorna ispitivanja na zavarenim spojevima s različitim parametrima. Dobiveni rezultati uspoređeni su sa normom HRN EN ISO 13919-2:2021, i odredila se razina kvalitete spojeva. Na temelju rezultata opisane su preporuke za pripremu i oblikovanje spojeva za ručno zavarivanje aluminija fiber laserom. Less

Abstract (english)

The objective of this thesis was to investigate and optimize the parameters of handheld laser welding of aluminum alloys, with a particular focus on the application of fiber lasers. The theoretical part analyzed various types of lasers used for welding thin-walled materials, with a detailed study of fiber lasers and their welding parameters. The interaction between the laser beam and the base material was examined, and the recommendations of the HRN EN 1011-6:2018 standard were studied. In the... More experimental part, non-destructive and destructive tests were conducted on welded joints with different parameters. The obtained results were compared to the HRN EN ISO 13919-2:2021 standard, and the quality level of the joints was determined. Based on the results, recommendations for the preparation and design of joints for manual aluminum welding with a fiber laser were described. Less
