Abstract

Cilj ovog rada je istražiti razlike prilikom zavarivanja uzdužnih greda Y-25 poluautomatskim i
robotskim MAG postupkom zavarivanja. Uzdužne grede se koriste za izgradnju postolja Y25
koja su predviđena za daljnju montažu teretnih vagona.

U teorijskom dijelu rada istraženo je koji se čelici koriste prilikom zavarivanja uzdužnih greda
Y-25, kakva je njihova zavarljivost te na što treba obratiti pozornost. Također je opisano što
predstavljaju uzdužne grede Y-25. Osim istraživanja čelika, opisan je način rada s
poluautomatski i robotskim MAG postupkom zavarivanja i njihovi parametri.

U eksperimentalnom dijelu prikazani su rezultati dobiveni prilikom zavarivanja uzdužnih greda
na okretnim postoljima robotskim MAG-om te usporedba kvalitete zavara s poluautomatskim
postupkom MAG zavarivanja.

Abstract (english)

The aim of this research paper is to explore differences between semi-automatic and robotic
MAG , whilst welding longitudinal beams Y-25. Longitudinal beams are used for construction
of Y25 boogies, which are further intended for assembly of freight cars.

In theoretical part of this research paper, it is explored what steel is is used for welding
longitudinal beam Y-25, steels weldability and where do we have to focus our attention in doing
so. Also it is described what longitudinal beam represent and what they are. In addition to steel
research, the way of working with semi-automatic and robotic MAG welding process are
described as well as their parameters.

In the experimental part of the research paper, the results obtained during the welding of
longitudinal beams on turntables with robotic MAG welding are compared to results of manual
MAG welding.
