Abstract
Oblikovno obločno navarjanje MIG/MAG predstavlja enega izmed postopkov dodajalnih tehnologij, ki zaradi svoje produktivnosti, vsestranskosti in cenovno dostopne opreme predstavlja velik potencial pri izdelavi velikih in hibridno izdelanih izdelkov. Naloga zajema pregled procesnih parametrov, ki omogočajo izdelavo ozke in ravne stene, navarjene na jekleno ploščo z varilno žico iz aluminijevega brona CuAl8. Na začetku so predstavljene osnove varjenja in spajkanja ter različni postopki in oprema za varjenje MIG/MAG. Raziskali smo vpliv različnih tehnoloških parametrov, na proces navarjanja, opravili smo analizo valovitosti stene in izkoristka navarjanja ter analizo stroškov. Ugotovili smo, da je za navarjanje aluminijevega brona najbolj primeren varilni proces CMT+P. Za izdelavo ozke in ravne stene pa je poleg ustreznih varilnih parametrov ključnega pomena medvarkovna temperatura, čistoča materiala, fine nastavitve na začetku in koncu varjenja ter pravilna izbira poti in hitrosti varjenja. Z opravljeno analizo smo določili stroške ter izkoristek navarjanja in valovitost stene.

Title:Fine adjustment of technological parameters for arc cladding of aluminium bronze
Abstract:
MIG/MAG wire are additive manufacturing is one of many additive technologies which is universal and affordable regarding investment costs and offers a huge potencial in producing bigger and hybrid made parts. This thesis covers defining of process parameters for making thin and streight wall cladded on a mild steel plate with aluminium bronze CuAl8 welding wire. In the first part of thesis we presented the basics of brazing and welding and also the different welding processes and equipment for MIG/MAG welding. We have researched the affects of different technological parameters on cladding process we made analysis of the wall shape, efficiency of cladding and process costs. We found out that for cladding aluminium bronze the welding proces CMT+P works best, but for making thin, streight wall besides the right welding parameters also the sample interpass temperature, cleanliness, fine adjustments on starts and stops of the welds and the correct welding path and speed are crucial. With the analysis made we determined the consumables costs, efficiency of cladding and wall shape.

Keywords:aluminium bronze, mild steel, MIG/MAG welding, welding process, process parameters, robotic welding, wire arc additive manufacturing
