MIG varjenje odlitkov in ekstrudiranih profilov iz aluminijeve zlitine : diplomsko delo Visokošolskega strokovnega študijskega programa I. stopnje StrojništvoTurk, Rok, strojnikPri varjenju ulitkov imamo izzive, saj prihaja do brizganja zaradi vključkov masti, ujetih plinskih mehurčkov in nečistoč, ki pod vplivom visoke energije tako spremenijo svoj volumen, da jih raznese. ... Prihaja tudi do poroznosti v zvaru, razpok, oz. slabše trdnosti spoja. Testirali smo varjenje odlitka EN AC-43500-T6 s profilom iz aluminijeve litine EN AW-6005-T6, z dodajnim materialom OK Autrod 4043. Pri aluminijevih zlitinah imamo dodatno težavo pri varjenju, ki nam jo povzroča oksidna plast. V začetku naloge je predstavljena teorija o postopku varjenja in o uporabljenih materialih, v nadaljevanju naloge pa skušamo ugotoviti pravilne parametre, načine varjenja in dejavnike pri varjenju, da bo zvar zagotavljal zadostno trdnost ter funkcionalnost. Varjenje poteka po postopku MIG/MAG s tehnologijo CMT. Pri testih je bil glavni povdarek na vplivu obdelanega zvarnega robu in lege gorilnika. Prišli smo do zakljčka, da je bolje da je obdelan ulitek oziroma oba v primeru, da varimo v dveh zaporednih korakih varjenja.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [R.
