FSW varjenje bakra : diplomsko delo Visokošolskega strokovnega študijskega programa I. stopnje StrojništvoŽnidaršič, JureV diplomskem delu smo prikazali varjenje dveh bakrenih zlitin Cu-HCP (CW0021A/C10300) in Cu-ETP (CW004A/C11000). Podrobneje smo opisali kemijsko sestavo bakra in opisali njegove fizikalne lastnosti. ... Na kratko smo podali opis legiranja bakra z drugimi elementi in nastanek zlitin po legiranju. Podrobneje smo opisali še zlitine, ki smo jih uporabili pri varjenju. Opisali in prikazali smo dva postopka varjenja, ki smo ju uporabili pri raziskovanju. To sta bila varjenje z gnetenjem in varjenje TIG, ki smo ju shematsko prikazali in popisali. Iz izdelanih zvarnih spojev smo izdelali makroobruse in vzorce za natezni preizkus. Za varjenje smo uporabili dva različna osnovna materiala, in sicer zato, ker smo uporabili dva različna postopka varjenja. Zato smo pri talilnem varjenju TIG izbrali baker, ki vsebuje fosfor, da se je kisik med procesom vezal na fosfor in zgorel. Pri varjenju FSW ne prihaja do taljenja materiala, saj se material segreje le do testastega stanja. Ugotovili smo, da vzorci zvarjeni po postopku varjenja z gnetenjem zdržijo manjše natezne napetosti kot vzorci varjeni s TIG. Izkazalo se je da, bi se ob uporabi primernejšega varilnega orodja kakovost zvara pri varjenju z gnetenjem povečala. Prav tako pride do razlik v mikrostrukturi zvarjenih kosov, ker pri talilnem varjenju vnesena temperatura vpliva na spremembo mikrostrukture osnovnega materiala in zvarnega spoja.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [J.
