Varjenje poliuretanske pene z vročim zrakom : diplomsko delo Visokošolskega strokovnega študijskega programa I. stopnje StrojništvoRamić, BelminPri vsakem postopku varjenja moramo določiti parametre in pogoje, pod katerimi bomo varili, ter na osnovi tega določiti najbolj optimalne parametre. V nalogi smo varili dve različni peni, ki se ... vizualno razlikujeta po barvi, pri tem ima vsaka različno gostoto. Za spajanje smo uporabili gorilnik na vroč zrak in pri vsakem eksperimentu smo glede na gostoto pene spreminjali temperaturo. Obe peni smo varili pri različnih pretokih zraka z uporabo dveh različnih šob. Nizek vnos energije ponazarja, da se polimer slabo raztali, kar ponazarja slabo kakovost zvara. Z druge strani, pri visokem vnosu energije pride do prekomernega pretaljevanja. Kakovost spoja smo preverili na osnovi vizualne ocene zvara, otipljive ocene trdote zvara in makroposnetka spoja. Pri izvedbi eksperimentov smo za varjenje uporabljali kose dimenzij 500 x 200 x 30 mm. Ugotovili smo, da gostota pene vpliva na tehnološke parametre in da pri povečevanju pretoka zraka potrebujemo manjšo temperaturo za varjenje. Na osnovi makroposnetka spojev smo opazili, da pri visokih temperaturah pride do večjega števila deformacij v celični strukturi in posledično do slabšega izkoristka surovca.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [B.
