1. Tajnikar, Žiga. Vpliv žarjenja za odpravo zaostalih napetosti na navarih zavarjenih po epp postopku.

Degree: 2018, Univerza v Mariboru

Magistrsko delo obravnava vpliv žarjenja za odpravo zaostalih napetosti na navarih, zavarjenih po postopku EPP. Za raziskavo so bili izdelani preizkušanci z navari, med katerimi so bili trije preizkušanci izpostavljeni različnim temperaturam žarjenja in četrti preizkušanec, ki je ostal v varjenem stanju brez žarjenja za odpravo zaostalih napetosti. Na preizkušancih je bila izmerjena stopnja deformacije s koordinatno merilno napravo in zaostale napetosti z magnetno metodo. Meritve so pokazale, da ima višina temperature žarenja pomemben vpliv na velikost zaostalih napetosti in stopnjo deformacije na preizkušancih. Ugotovljeno je bilo, da učinkovitost žarjenja s temperaturo narašča le do maksimalne temperature, ki je odvisna od izbranega osnovnega in dodajnega materiala. Z nadaljnjim zvišanjem temperature se učinkovitost žarjenja ponovno zmanjša.

The master thesis at hand deals with the influence of annealing for relaxation of residual stress on specimens, clad welded with the SAW process. For this research, four specimens were prepared, of which three were exposed to different annealing temperature and the fourth specimen remained in its original (as-welded) condition. Strain on the speciments was measured using coordinate measuring device and the residual stress was measured using magnetic method. Results revealed that the annealing temperature has a major influence on the level of the residual stress and strain on the test pieces. This proves that the efficiency of annealing with temperature increases only to a certain maximum temperature, which depends on the selected basic and the feed material. Continuous increase in temperature will decrease the efficiency of annealing.
