Vpliv zaščitnih plinov pri TIG varjenju bakra : magistrsko delo magistrskega študijskega programa II. stopnje StrojništvoČubej, MatevžPrimaren proces za spajanje bakrenih električnih kontaktov je v preteklosti bilo spajkanje. Spajkanje sicer daje odlične rezultate z vidika zagotavljanja prevodnosti kontakta, vendar je časovno ... zamuden, zahteven za izvedbo ter problematičen za avtomatizacijo. Zaradi želje po zmanjšanju časa cikla in posledično stroškov se je kot alternativa pojavilo varjenje TIG. Dobršen del stroškov obratovanja TIG varilne celice predstavlja zaščitni plin. Raziskovali smo možnost implementacije zaščitnega plina dušika v proces ter njegov vpliv na kakovost spoja. Rezultate smo primerjali s standardno uporabljenimi zaščitnimi plini, tj. argonom in helijem. Ovrednotili smo jih vizualno ter številčno z uporabo nateznega preizkusa in analizo mikrostrukture zvarov. Prišli smo do zaključkov, da z uporabo dušika kot zaščitni plin doseganje predpisanih zahtev, z izjemo vizualne, ni mogoče dosegati. Primerjava z inertnima zaščitnima plinoma je potrdila tezo, da zvarni spoji izvedeni v zaščitni atmosferi inertnega plina ustrezajo vsem zahtevam. Izvedena stroškovna analiza je potrdila končni izbor zaščitnega plina argona za nadaljnjo proizvodnjo.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [M.
