20.500.12556/RUL-101456 Oblikovno navarjanje aluminijeve zlitine AlSi5 Wire and Arc Additive Manufacturing of AlSi5 Aluminum Alloy Aluminijeve zlitine se veliko uporabljajo pri izdelavi raznih izdelkov, pri katerih je pomembno visoko razmerje med trdnostjo in maso. Pri izdelavi kompleksnih izdelkov pogosto naletimo na tehnološke omejitve izdelave, ali pa želimo zmanjšati stroške in količino odpadnega materiala. Zato se v zadnjem času čedalje bolj uveljavljajo aditivne tehnologije, s katerimi rešujemo te izzive. Naloga se osredotoča na izdelavo baze podatkov pri obločnem navarjanju aluminijeve zlitine AlSi5 in optimiziranje postopka. Testi so opravljeni z varilnim robotom in sinergijskim varilnim virom za varjenje MIG/MAG, uporabljen pa je postopek CMT. Predvsem so podrobno preučeni osnovni varilni parametri, ki omogočajo izdelavo kakovostnih navarjenih sten, analizirano pa je tudi odvajanje toplote in razporeditev le-te po varjencu. Izsledki naloge kažejo, da je ob dobrem obvladovanju vnosa toplotne energije mogoče izdelati vizualno kakovostne stene s širino do 4,5 mm in izkoristki materiala nad 80 % , ki jih je po dodatni mehanski obdelavi možno uporabiti za izdelavo tankostenskih izdelkov. Aluminum alloys are used in the manufacturing of many products that require a high strength to weight ratio. In manufacturing of complex products we often reach the technological limits of conventional manufacturing methods or want to reduce costs and the amount of discarded material. To solve these problems, many types of additive technologies are being developed. This paper focuses on creating a database of parameters and optimization of the wire and arc additive manufacturing method for welding of AlSi5 aluminum alloy. The tests are made using a welding robot in combination with a synergic MIG/MAG welding machine and where CMT welding process is used. The emphasis is on the study of core welding parameters that enable quality welded walls to be made. Heat conduction and its distribution across the welded part is also studied. The results of this paper show that through good heat input management, it is possible to produce quality welded walls with widths up to 4,5 mm and material deposition efficiency above 80 % that, after additional machining, can be used for production of thin-walled products. aluminijeve zlitine varjenje aluminij AlSi5 postopki spajanja materialov aditivne tehnologije navarjanje WAAM 3D tiskanje aluminum alloys welding aluminum AlSi5 material joining processes additive technologies WAAM 3D printing true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2018-06-06 07:45:02 2018-06-06 07:45:12 2022-08-14 03:44:38 0000-00-00 00:00:00 2018 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 204532 1724.pdf 1724.pdf 1 F9625B11CD019FC8BDE448AD47438446 24501462cffc4fec32956782eabc5e37a563587651faa11853ce5cf9b76d258e 447f3df5-a1b5-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=111480 Fakulteta za strojništvo 0 0 0
