Spajanje poliuretanskih pen - PUF različnih gostot z vročim zrakom : zaključna naloga Univerzitetnega študijskega programa I. stopnje Strojništvo - Razvojno raziskovalni programPerko, KristjanZa kakovostno spajanje poliuretanskih pen z vročim zrakom, je potrebno določiti optimalne parametre varjenja. V nalogi smo varili pene različnih gostot z različnimi temperaturami zraka in dimenzijami ... šob. Med spajanjem je bila hitrost varjenja in oddaljenost šobe od pene konstantna. Prenizek vnos energije rezultira v premajhno količino raztaljenega materiala in nižjo trdnost spoja. Pri prevelikem vnosu energije pa lahko pride do prekomernega pretaljevanja materiala, nižjo trdnost spoja zaradi manjšega prečnega preseka in na otip tršega zvara. Izvedli smo preizkusno varjenje z vročim zrakom v okviru vnaprej določenih procesnih parametrih. Zvare smo vrednotili po treh kriterijih: izvedli vizualno oceno zvarnega spoja, mesto pretrga pri natezno-strižnem preizkusu (na spoju ali v osnovnem materialu) in trdoto zvara na otip. Ugotovili smo, da gostota pene močno vpliva na izbor procesnih parametrov. Za naše primere varjenje smo na podlagi eksperimentov določili za najbolj primerne parametre šobo dimenzij 20 mm x 2,5 mm in spajanje s stopnjo gorilnika 3,5.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [K.
