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 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.

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 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.
