Lasersko varjenje bakra in bakrovih zlitin : zaključna naloga univerzitetnega študijskega programa I. stopnje Strojništvo
Novak, Blaž, 1993-
Baker in njegove zlitine so v industriji, predvsem avtomobilski, ene izmed najbolj uporabljenih elementov. Njegovo pomembnost nam pove že dejstvo, da se po njem imenuje obdobje prazgodovine. Izziv ...pri varjenju bakra (npr. pri varjenju z IR ali zeleno svetlobo) je v tem, da ima visoko reflektivnost, visoko termično prevodnost, ter nizko prevodnost. Zaradi tega ga je izredno težko variti že z laserji, saj baker potrebuje močan vir toplote. V zaključni nalogi smo pregledati najnovejšo znanstveno literaturo na področju varjenja in varivosti bakra in njegovih zlitin. Opisani so vplivi laserske svetlobe na varivost in njeno absorptivnost, vpliv zaščitnih plinov na varivost in metalurške lastnosti zvarnega spoja. Ugotovili smo, da je za varjenje bakra in bakrovih zlitin primerno variti z kombinacijo IR in zelene svetlobe ali preprosto kar z zeleno svetlobo. Najprimernejša svetloba za varjenje bakra je modra, saj z njo dosežemo največjo absorpcijo energije
