20.500.12556/DKUM-74193 Optimizacija spenjanja in varjenja stebra žerjava magistrsko delo Optimization of stapling and welding of crane column Naša naloga je bila optimizirati varjenje stebra žerjava v podjetju Palfinger d.o.o. Izvedli smo porušne in neporušne preiskave in določiti pomembne lastnosti materiala – natezno trdnost, napetost tečenja, žilavost… Določili smo potrebno temperaturo predgrevanja, ki znaša 140,23 °C. Z zamenjavo plamenskega predgrevanja z induktivnim smo opazno zmanjšali čas celotnega postopka. Z optimizacijo postavitve delovnega mesta smo dosegli enostavnejšo napeljavo za induktivno napravo in možnost rabe ene naprave za dve delovni liniji. Ugotovili smo, da bi z zamenjavo robotske celice s celico s šestimi osmi in dvema eksternima osema, kar bi omogočalo postavitev vseh varov v PA položaj varjenja, dosegli kvalitetnejše zvare in krajše čase poobdelave ter popravil. Our task was to optimize the welding of the crane column at Palfinger d.o.o. Destructive and non-destructive tests were carried out and important material properties were determined - tensile strength, toughness… The required pre-heating temperature was determined to be 140.23 ° C. By replacing the flame preheater with the inductive one, we noticeably reduced the time of the whole process. By optimizing the layout of the workplace, we have achieved a simpler installation for the inductive device and the possibility of using one device for two work lines. We found that replacing the robot cell with a cell with six axes and two external axes, which would allow the placement of all welds in the PA welding position, would achieve better welds and shorter times for repairs. varjenje robotsko varjenje induktivno predgrevanje porušne preiskave neporušne preiskave welding robotic welding inductive preheating destructive testing non-destructive testing true true false [N.
