Tehnološka in ekonomska primerjava varjenja MIG/MAG in CMT : diplomska naloga univerzitetnega študija
Jerič, Uroš, strojnik
V diplomi smo se osredotočali na stroškovno analizo robotskega MIG/MAG varjenja. Naredili smo optimizacijo varilnih parametrov, da odpravimo brizganje pri varjenju kotnih zvarov stebrov in varjenju ...pocinkanih vijakov v stebričkih. V teoretičnem delu je opisan postopek MIG/MAG, posodobljeni postopek MIG/MAG ter med drugim sam postopek CMT. Opisana je tudi težava brizganja ter opisan izračun stroškov pri varjenju. Praktični del naloge obsega poizkusno varjenje kotnih zvarov in varjenja pocinkanih vijakov. Naredili smo makroobruse, vizualno kontrolo varov in na njih izmerili trdoto ter ustreznost višine kotnega zvara. Zvare vijakov smo testirali na potreben vrtilni moment vijačenja. Izdelali smo primerjavo stroškov varjenja optimalnega CMT varjenja glede na obstoječe varjenje v podjetju (pulzno varjenje). Rezultati varjenja so pokazali, da je po CMT postopku mogoče variti zelo kakovostno in ceneje, kljub varjenju v zaščitni atmosferi ogljikovega dioksida. Pri varjenju zahtevane višine kotnega zvara smo dosegli spajanje skoraj brez brizganja.
