20.500.12556/RUL-188218 Adaptivno vertikalno vodenje WAAM procesa z zaznavo geometrijskih odstopanj Adaptive control of WAAM deposition based on real-time geometric sensing Obločno navarjanje z žico (WAAM) omogoča izdelavo velikih kovinskih komponent, vendar kakovost izdelkov omejujejo geometrijska odstopanja med navarjanjem. V magistrski nalogi obravnavamo vertikalno prilagajanje elektrode z uporabo funkcije AVC ter možnost zaznavanja in odpravljanja nastalih defektov. V sklopu magistrske naloge smo izdelali eksperimentalni sistem za zajemanje in obdelavo podatkov, potrebnih za spremljanje geometrije posameznih navarjenih plasti ter zaznavanje napak med postopkom WAAM. Na podlagi eksperimentalnih meritev smo določili karakteristiko varilnega obloka in analiziran odziv AVC pri različnih geometrijah ter stopnjah ojačanja. Ugotovili smo, da je bila pri uporabljenih pogojih najprimernejša stopnja ojačanja 60. Z obdelavo napetosti varilnega obloka in podatkov o poti elektrode je bilo mogoče rekonstruirati profil vsake navarjene plasti ter zaznati in odpraviti geometrijska odstopanja z dodatnimi navarki. Rezultati potrjujejo možnost uporabe obločne napetosti za sprotno spremljanje geometrije navarjenih plasti in povečanje stopnje avtomatizacije postopka WAAM. Wire Arc Additive Manufacturing (WAAM) enables the production of large metal components; however, product quality is limited by geometric deviations during deposition. This thesis investigates vertical electrode adjustment using the Automatic Voltage Control function (AVC), as well as the detection and correction of resulting defects. An experimental system was developed for acquiring and processing data required to monitor the geometry of individual deposited layers and detect defects during the WAAM process. Based on experimental measurements, the arc voltage characteristic was determined, and the AVC response was analysed for different geometries and gain levels. Under the investigated conditions, a gain level of 60 was found to be the most suitable. By processing welding arc voltage and electrode path data, the profile of each deposited layer could be reconstructed, allowing geometric deviations to be detected and corrected by additional deposition. The results confirm the feasibility of using arc voltage for real-time monitoring of deposited layer geometry and increasing the level of automation in the WAAM process.
