The most important welded joints and claddings are treated, however, all the welded joints and claddings could not be treated because there are around 60000 in each steam generator. First cladding of the inner surface of the primary head of the steam generator is described. Submerged-arc cladding with a strip electrode was used for this purpose. Then the production of the welded joints between a tube and a tube sheet is described. All 5428 tubes were joined to the tube sheet, at each end, by TIG welding, preceded by mechanical rolling-in and hydraulic expansion.Welding of a partition plate to the primary head and to the tube sheet is described in the third part of the paper. Both welded joints, i.e. the one between the partition plate and the tube sheet and the one between the partition plate and the primary head, are shown as macro section. Finally, welding of circumferential welds at the steam-generator shell is described. Two different arc welding processes were used for the purpose. The weld root was manually arc welded with a covered electrode while other welds were automatically submerged-arc welded. In the conclusions, it is stated that the welding technologies used were selected properly and well controlled during execution, which ensured the quality of the steam generator"},{"@xml:lang":"sl","#text":"V članku je opisana tehnologija zvarjanja in navarjanja uporabljena pri izdelavi uparjalnikov za Jedrsko elektrarno Krško. Predstavljeni so najpomembnejši zvarni spoji in najpomembnejši navari. Vseh zvarnih spojev in varov pa ni bilo mogoče predstaviti, saj jih je samo v enem uparjalniku okrog 60000. V prvem delu članka je opisano navarjanje notranje površine primarne glave uparjalnika. Uporabljeno je bilo navarjanje s tračno elektrodo pod praškom. V drugem delu je predstavljena izdelava zvarnih spojev med cevjo in cevno steno. Vseh 5428 cevi je spojenih s cevno steno na dveh koncih z obločnim varjenjem TIG ter hidravlično ekspanzijo in mehanskim uvaljanjem. Varjenje predelne stene na primarno glavo in cevno steno je opisano v tretjem delu članka. Z makro obrusom sta predstavljena oba zvarna spoja predelne stenes cevno steno in s primarno glavo. V zadnjem delu pa najdemo opis varjenja krožnih varov na plašču uparjalnika. Tu sta bila uporabljena dva različna obločna postopka varjenja. Koren vara je bil varjen z oplaščeno elektrodo, preostali vari pa avtomatsko pod praškom. Na koncu članka so podani sklepi v katerih je navedeno, da so bile tehnologije varjenja pravilno izbrane in med izvajanjem zelo dobro načrtovane, kar je zagotovilo, da je uparjalnik izdelan zelo kakovostno"}],"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-7JRGAK7G","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-7JRGAK7G"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-7JRGAK7G/a5a9de81-8277-47c1-a5e6-77bbec5b03a8/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":"Univerza v Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-7JRGAK7G/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-7JRGAK7G"}}}}
