Oblikovno navarjanje konstrukcijskega jekla : zaključna naloga univerzitetnega študijskega programa I. stopnje StrojništvoGovednik, MarkoObločno navarjenje z dodajanjem žice je novejša tehnologija izdelave 3D izdelkov, ki danes predstavlja zelo dobro alternativo tradicionalnim postopkom odrezavanja pri izdelavi kompleksnih izdelkov in ... uporabi dragih kovin. Trenuten poudarek raziskav na tem področju je izboljšava geometrijske natančnosti in površinske hrapavosti izdelkov kompleksnih oblik ter zmanjšanje zaostalih napetosti, ki so posledica termično inducirane obremenitve z obločnim virom toplote. Ugotavljali smo vpliv različnih parametrov navarjanja in strategij gradnje varkov na izgled in izkoristek navarjenega materiala. Ugotavljali smo, vpliv kota gorilnika pri varjenju poševnih sten in vpliv le tega na izkoristek materiala. Raziskovali smo vplive stopnje prekrivanja varkov na zlepe oziroma neprevarjenost izdelka ter vpliv medvarkovne temperature. Z večanjem hitrosti varjenja se višina in širina stene manjšata, ne glede na parametre in strategijo varjenja, ker se navari manj materiala. Izkoristki sten se bistveno ne spreminjajo s spreminjanjem varilnih parametrov in strategij izdelave in so približno enaki pri navarjanju ravnih in poševnih sten. Z večanjem prekrivanja med varki se večajo zlepi znotraj stene, medtem ko se manjšajo z večanjem medvarkovne temperature.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [M.
