A plan of experiments was prepared based on the abilities of a universal milling machine, where the tool-rotation speed varied from 200 r/min to 1250 r/min, the welding speed from 71 mm/min to 450 mm/min and the tool tilt angle was held constant at 2. The factors feed per revolution (FPR) and revolution per feed (RPF) were introduced to get a better insight into the friction-stirring process. Samples for microstructure analyses, Vickers micro-hardness measurements and special miniature tensile-testing samples were prepared. The microstructure was prepared for observation on a light microscope under a polarised light source. A set of optimal welding parameters was determined at a FPR of 0.35 mm/r, at which quality welds can be made with a minimal increase in the weld hardness and an up to 15 % drop in the tensile strength"},{"@xml:lang":"sl","#text":"Izdelana je študija varivosti 4 mm debele pločevine iz aluminijeve zlitine 5083 pri varjenju s trenjem in mešanjem. Načrt eksperimentov je bil pripravljen na podlagi sposobnosti univerzalnega frezalnega stroja. Spreminjali smo hitrost vrtenja orodja od 200-1250 r/min, hitrost varjenja 71-450 mm/min, kot nagiba orodja pa je bil konstanten pri 2°. Vpeljana sta bila faktorja podajanje na vrtljaj (FPR) in obratov na podajanje (RPF), s katerima bolj nazorno prikažemo vpliv parametrov procesa. Iz izdelanih varov smo pripravili vzorec za analizo mikrostrukture, vzorec za meritev trdote po Vickersu ter posebne miniaturne epruvete za natezni preizkus. Mikrostruktura je bila pripravljena za opazovanje na svetlobnem mikroskopu v polarizirani svetlobi. Optimalni parametri varjenja so bili ugotovljeni pri FPR 0,35 mm/r, pri čemer dobimo kakovostne zvare, z minimalnim povečanjem trdote vara in do 15-odstotnim padcem natezne trdnosti"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-CJP1NJBK","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-CJP1NJBK"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-CJP1NJBK/349d9e26-75e4-4e20-b5f6-c6113613a656/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Inštitut za kovinske materiale in tehnologije"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-CJP1NJBK/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-CJP1NJBK"}}}}
