Ultrazvočno varjenje bakrenih žic na bakrene obročke : magistrsko delo magistrskega študijskega programa II. stopnje Strojništvo
Rončević, Tomaž
V magistrskem delu je predstavljen problem varjenja bakrenih žic na bakrene obročke v podjetju MAHLE Letrika d.o.o.. V delu je opisan postopek ultrazvočnega varjenja v primerjavi s postopkom ...spajkanja, kakor se trenutno izvaja na proizvodni liniji. Opisani so vsi uporabljeni materiali in metode, načrt eksperimentov ter izvedba ultrazvočnega varjenja bakrenih žic na bakrene obročke. Glede na preliminarni test smo dobili okvirne parametre, ki so se gibali okoli tv = 0,60 s in amplitude Amp % 5. Izdelani spoji so neporušno pregledani vizualno in testirani na električno upornost. Pri porušni metodi preiskav pa je bil izveden trdnostni preizkus in metalografska analiza makroobrusov. Na koncu sledi še primerjava, analiza in ocena rezultatov ultrazvočno varjenih (UZ) spojev s spajkanimi spoji.
