Varjenje z gnetenjem aluminijeve zlitine z bakrom : diplomska naloga univerzitetnega študija
Gračnar, Bojan
Cilj diplomske naloge je raziskati spajanje aluminijeve zlitine 6082 z bakrom Cu ETP ter ugotoviti najprimernejše parametre varjenja in orodje za varjenje. V teoretičnem delu smo opisali postopek ...varjenja z gnetenjem ter materiale in metode, uporabljene pri preizkusih. V eksperimentalnem delu smo izdelali in uporabili več različnih oblik orodja. Varjenje smo izvajali z različnimi parametri varjenja. Iz izdelanih spojev smo pripravili vzorce za izdelavo makroobrusov, vzorce za izdelavo nateznih testov ter vzorce za testiranje s temperaturnim utrujanjem. Vzorce smo nato testirali in naredili analize. Ugotovili smo, da že pri majhnih odstopanjih varilnih parametrov dobimo zelo različne rezultate nateznih trdnosti in tudi različne vizualne kvalitete spoja. Kljub temu smo zvarili spoj z zadovoljivo natezno trdnostjo, ki je znašala nad 217,5 MPa, kar predstavlja 75 % natezne trdnosti šibkejšega varjenca.
