Helium is also often added to the argon. The effect of the type of shielding gas - argon, nitrogen, helium and their mixtures - on the geometrical characteristics of laser-welded joints of the duplex steel W.Nr. 1.4462 was studied. The welding was carried out according to the experimental model with mixtures. The effect of the welding speed and the gas flow rate were additionally explored using a factorial experiment. The obtained data were statistically processed and mathematical modeling, applying the method of response surfaces, was carried out. The analysis revealed that the impact of the shielding gas mixtures on the geometrical characteristics of the joint is significant. The effect of the gas flow rate on the geometrical characteristics was registered, while the effect of the heat input is the most significant. Special cubic, quadratic and reduced quadratic models, depicting the effects of the shielding gases on the geometrical characteristics of the welded joint, were obtained</dc:description><dc:description xml:lang="sl">Pri laserskem varjenju dupleksnega jekla se kot zaščitna plina večinoma uporabljata čisti argon in mešanica argona z dušikom, pogosto pa se k argonu dodaja tudi helij. Pri laserskem varjenju dupleksnega jekla W.Nr. 1.4462 se je preučeval vpliv vrste zaščitnega plina: argona, dušika, helija in njihovih mešanic, na geometrijske značilnosti zvarov. Varjenje je bilo izvedeno po eksperimentalnem modelu z mešanicami. Na osnovi faktorskega eksperimenta je bil preučen tudi vpliv hitrosti varjenja in pretoka zaščitnega plina. Dobljeni rezultati so bili statistično ovrednoteni in ustvarjen je bil matematični model po metodi odzivnih površin. Rezultati tako dobljene analize razkrivajo, da je vpliv zaščitnega plina na geometrijske značilnosti zvarov signifikanten. Ob opaznem vplivu pretoka zaščitnega plina na geometrijske značilnosti zvara je očitno dejstvo, da je najbolj signifikanten vnos toplote. Dobljeni so bili posebni kubični, kvadratični in reducirani kvadratični modeli geometrijskih značilnosti zvarov</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-BC8OKJS8"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-BC8OKJS8" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-BC8OKJS8/992dbb1d-f296-440d-8e43-8bca5453fe10/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Inštitut za kovinske materiale in tehnologije</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-BC8OKJS8/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-BC8OKJS8" /></ore:Aggregation></rdf:RDF>
