20.500.12556/DKUM-84895 Robotsko varjenje cevnih jeklenih zvarnih spojev diplomsko delo Robotic welding of tubular steel welded joints Cilj diplomske naloge z naslovom Robotsko varjenje cevnih jeklenih zvarnih spojev je bil raziskati in ovrednotiti učinkovitost ter kakovost avtomatiziranega varilnega postopka pri spajanju cevnih jeklenih elementov. Poudarek je bil na primerjavi med tradicionalnimi ročnimi varilnimi metodami in sodobnim robotskim varjenjem. Analizirali smo, kako se mehanske lastnosti, kot so trdota in žilavost zvarov, spreminjajo z uporabo robotskega varjenja. Prav tako smo preučili mikrotrdoto različnih območij zvarnega spoja, vključno z osnovnim materialom, toplotno vplivanim področjem in samim varom. Naloga prav tako obravna pomen pravilne priprave materiala pred varjenjem in optimizacijo parametrov varilne opreme. The objective of the diploma thesis was to investigate and evaluate the efficiency and quality of the automated welding process in joining tubular steel elements. Emphasis was placed on comparing traditional manual welding methods with modern robotic welding. We analyzed how mechanical properties, such as hardness and toughness of welds, change with the use of robotic welding. We also studied the microhardness of various areas of the welded joint, including the base material, heat-affected zone, and the weld itself. The study also addressed the importance of proper material preparation before welding and the optimization of welding equipment parameters. robotsko varjenje cevni zvarni spoj mikrotrdota kemična analiza toplotno vplivano področje robot welding pipe weld joint microhardness chemical analysis heat affected area true true false [A.
