20.500.12556/DKUM-62813 ATIG varjenje nerjavnega jekla in določanje mehanskih lastnosti zvarnega spoja ATIG welding of stainless steel and determing the mechanical properties of welded joints Cilj diplomske naloge je bilo varjenje z ATIG postopkom in uporaba dveh različnih aktivatorskih praškov – zelenega in belega. Naloga je eksperimentalne narave, kjer nas je zanimalo, kateri izmed dveh praškov se bo bolje obnesel pri TIG varjenju pod različnimi varilnimi parametri. Eksperiment je bil izveden za vsak prašek posamezno, nato pa še v vlogi obeh praškov (Z + B) v razmerju 50 : 50. Zanimalo nas je tudi obnašanje materiala pri nateznem preizkusu, kjer smo naredili primerjavo med praškoma, njuno mešanico in TIG varjenjem. Rezultati so pokazali, da sta praška učinkovitejša, če nastopata kot mešanica, v razmerju 50 : 50. Dokazali smo tudi, da za dobre lastnosti vara, ne potrebujemo najvišjega varilnega toka ali največje varilne napetosti. The aim of the diploma was ATIG welding procedure and application of two different activator powders (green and white powder). The diploma is of experimental nature, where we wanted to find out which of the two powders is better in TIG welding under various welding parameters. The experiment was carried out for each powder separately and then in the application of both powders (G + W) in a ratio of 50 : 50. We were interested in the behavior of the material in a tensile test, in which we were comparing between the green and white powder, a mixture of both of them (ratio 50 : 50) and in TIG welding. We also proved that for a quality weld we do not need the highest weldint current or a maximum welding voltage.
