Abstract

U ovom radu prikazana je procedura zavarivanja čelične konstrukcije sklopa srednje grede. U
uvodnom dijelu rada je predstavljen sklop srednje grede kao dio konstrukcije elektromotornog
vlaka tvrtke Končar – Električna vozila. Zatim je predstavljena tvrtka ZM-Vikom čija je obveza
proizvesti cjelokupnu konstrukciju modula elektromotornog vlaka. Opisana je tehnologija
zavarivanja sklopa kroz opis nelegiranog konstrukcijskog čelika S355, MAG postupka
zavarivanja te žice za zavarivanje. Prikazan je način definiranja procesa zavarivanja, a samim
time i proizvodnje čelične konstrukcije, u skladu s normom HRN EN 15085: Željeznički sustav
-- Zavarivanje željezničkih vozila i sastavnih dijelova. U eksperimentalnom dijelu rada
osmišljena je procedura zavarivanja sklopa srednje grede korištenjem modularnog pristupa
prilikom analize procesa izrade konstrukcije uz dokumentiranje procesa izrade koji se izvršava
korištenjem naprava za sastavljanje i zavarivanje. Podjelom procesa zavarivanja u više koraka
rada uz definiranje svih radnji kojima se proces zavarivanja provjerava i potvrđuje razvijena je
procedura koja nailazi na prihvaćanje. Na temelju razvijene procedure osmišljen je koncept
radnih procedura primjenjiv za analizu procesa zavarivanja i načina njegova provođenja.
Naposlijetku je iznesen zaključak rada.

Abstract (english)

In this paper, the welding procedure of the steel structure of the central beam assembly is presented. In the introductory part of the paper, the central beam assembly is presented as part of the design of the Končar – Električna vozila electric train. Then, the company ZM-Vikom was presented, whose obligation is to produce the entire design of the electric train module. The welding technology of the assembly is described through the description of non-alloy structural steel S355, MAG welding process and welding wire. The method of defining the welding process, and thus the production of steel structures, in accordance with the standard HRN EN 15085: Railway system - Welding of railway vehicles and components is presented. In the experimental part of the paper, the welding procedure of the central beam assembly was designed using a modular approach when analyzing the design process with documenting the manufacturing process performed using assembly and welding devices. By dividing the welding process into several steps of work with the definition of all actions by which the welding process is checked and confirmed, a procedure has been developed that is accepted. Based on the developed procedure, the concept of working procedures applicable to the analysis of the welding process and the manner of its implementation has been developed. Finally, the conclusion of the paper was presented.
