20.500.12556/RUL-160460 Lasersko čiščenje zvarov na nerjavnem jeklu AISI 304 Laser cleaning of welds made on stainless steel AISI 304 Optimizacija procesov v industriji je ključna za konkurenčnost, pri čemer ima pomembno vlogo uporaba laserjev. Nerjavno jeklo, zaradi svoje korozijske odpornosti, pogosto potrebuje obdelavo po varjenju, saj varjenje poškoduje zaščitno oksidno plast. Namen naloge je bil raziskati možnost optimizacije procesa varjenja in čiščenja zvara nerjavnega jekla z uporabo kontinuirnega laserja. Spreminjali smo parametre čiščenja, kot so oddaljenost od gorišča laserskega snopa, moč in hitrost skeniranja. Rezultate smo vizualno ocenili in postavili v matriko. Ugotovili smo, da zaradi prevelikega vnosa toplote, površina ni le očiščena, pač pa tudi delno pretaljena. Optimization of processes in industry is crucial for competitiveness, with lasers playing an important role. Stainless steel, due to its corrosion resistance, often requires treatment after welding, as welding damages the protective oxide layer. The aim of this thesis was to explore the possibility of optimizing the welding and cleaning process of stainless steel welds using a continuous laser. We varied cleaning parameters such as the distance from the laser beam focal point, power, and scanning speed. The results were visually assessed and organized into a matrix. We have determined that surface is not only cleaned, but also partially melted. lasersko čiščenje nerjavno jeklo lasersko varjenje kontinuirni laser oksidne plasti toplotna obarvanost laser cleaning stainless steel laser welding continuous laser oxide layers heat tint true false false Slovenski jezik Angleški jezik Zaključna naloga 2024-08-29 07:30:34 2024-08-29 07:30:37 2024-11-08 11:06:06 0000-00-00 00:00:00 2024 0 0 XII, 30 f. 2024 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.791.725:669.14:536(043.2) 263698 214225155 34101.pdf 34101.pdf 1 6779B366CB399890BA8317AB98B33376 bafe0615dbdd8037d0dcb501e9d58f7375beba071777d3579062775cfb6cb195 97c5137e-65c7-11ef-8f74-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=189157 Fakulteta za strojništvo 0 0 0
