20.500.12556/DKUM-87216 Uporaba različnih postopkov navarjanja za izboljšanje obrabne obstojnosti magistrsko delo Use of different hardfacing methods to enhance wear resistance Navarjanje je pomemben postopek povečevanja obrabne obstojnosti strojnih delov. V magistrski nalogi sta predstavljena postopka navarjanja z MAG tehnologijo in s PTA tehnologijo. Izvedli smo navarjanje z dodajnimi materiali, ki so trenutno v uporabi v podjetju Farmtech d. o. o., in jih primerjali z novima za uporabo s PTA in MAG tehnologijo. Za primerjavo smo izvedli test obstojnosti proti obrabi, meritev trdot v prerezu talonov in meritev površin namešanja. To smo nadgradili tudi s stroškovno in časovno analizo. Rezultati bodo služili kot smernice za odločitev k implementiranju PTA tehnologije v obstoječo proizvodnjo. Overlay welding is an important process for increasing the wear resistance of machine parts. In the master’s thesis, two welding processes are presented with MAG technology and PTA technology. We carried out welding with additive materials, which are currently in use in the company Farmtech d. o. o., and compared them with new ones for use with PTA and MAG technology. For comparison, we carried out a wear resistance test, hardness measurement in the cross-section of the samples, and measurement of mixing areas. We also upgraded this with a cost and time analysis. The results will serve as guidelines for the decision to implement PTA technology in existing production. navarjanje obrabna obstojnost obrabni preskus PTA tehnologija navarjanja MAG tehnologija navarjanja overlay welding wear resistance wear test PTA welding overlay process MAG welding overlay process true true false [D.
