20.500.12556/DKUM-11048 PRIMERJAVA MED EKONOMIČNOSTJO IN MEHANSKIMI LASTNOSTMI PLOŠČ IZ ALUMINIJEVE ZLITINE COMPARISON BETWEEN EFFECTIVENESS AND MECHANICAL PROPERTIES OF AL-ALLOYS PLATE V diplomskem delu je obravnavana primerjava med TIG in TVG postopkom varjenja plošč iz aluminijeve zlitine. Primerjava je opravljena iz tehničnega in ekonomskega vidika. Namen naloge je spoznati značilnosti obeh postopkov in na osnovi izsledkov opredeliti primernejši postopek z vidika ekonomičnosti in mehanskih lastnosti. Določitev in analiza mehanskih lastnosti materiala je bila opravljena na osnovi nateznega preizkusa. Da bi ugotovili kateri postopek je bolj ekonomičen smo opravili analizo proizvajalnih stroškov varjenja. Rezultati mehanske analize ne kažejo velikih odstopanj. Nekoliko boljše mehanske lastnosti imajo preizkušanci zvarjeni s TVG postopkom. Z vidika ekonomičnosti je kljub visokim investicijskim stroškom stroškovno ugodnejši TVG postopek, predvsem zaradi večje hitrosti varjenja. This diploma work discusses the comparison between the TIG and TVG welding processes for Al-Alloy plates. The comparison is based on a technical and economic point of view. The aim of this work is to present the characteristics of both processes and define the most appropriate one from an economical aspect and with regard to its mechanical features, according to the acquired data. The determination and analysis of the material's mechanical properties is founded on a tensile test. To clarify which process is most economical, we conducted an analysis of welding costs. The results of the mechanical analysis do not point to any extreme discrepancies. The test-objects produced by the means of a TVG welding process have somewhat better mechanical features. From an economical aspect, though carrying the highest investment costs, the TVG welding process is more favourable, mostly due to its higher welding speed. varjenje TIG varjenje torno varjenje z gnetenjem zvarni spoj mehanske lastnosti aluminijeve zlitine natezni preizkus ARAMIS stroški varjenja ekonomska analiza analiza stroškov ekonomičnost welding TIG welding Friction stir welding weld joint mechanical properties Al-Alloys tensile test ARAMIS weld costs economic analysis cost analysis effectivenes true true false [M.
