Abstract

U ovom radu provedena je specifikacija proizvodnih zahtjeva za izradu zavarene konstrukcije transformatorskog kotla prema normi HRN EN 15085. Norma postavlja opće smjernice za zavarivanje željezničkih vozila i komponenti. U tekstu su detaljno razmatrani zahtjevi norme te je posljedično izrađen plan kontrole i inspekcija uključujući dodatne zahtjeve naručitelja sa stanovišta izrade radnih proba. U eksperimentalnom dijelu na određenim sekcijama transformatorskog kotla provedena su odgovarajuća ispitivanja, sukladno definiranom planu kontrole. Prikazana su tražena izvješća i dokumentacija sukladno normom HRN EN 15085. Zaključno, provedena je analiza kritičnih mjesta u proizvodnji zavarivanjem koja imaju najveći utjecaj na kvalitetu proizvoda te je ocijenjena prikladnost postojećeg sustava za primjenu zahtjeva HRN EN 15085.

Abstract (english)

In this final thesis, the specification of production requirements for the fabrication of a welded construction of a transformer tank was carried out according to the standard HRN EN 15085. The standard provides general guidelines for welding railway vehicles and its components. The text thoroughly discusses the standard requirements, and consequently, an Inspection and testing plan is developed, including additional requirements from the client’s perspective regarding the creation of working samples. In the experimental part of thesis, appropriate tests were conducted on specific sections of the transformer tank, in accordance with the defined control plan. The required reports and documentation are presented in accordance with the HRN EN 15085 standard. In conclusion, an analysis of critical welding points in the production was conducted, identifying those with the greatest impact on product quality, and the suitability of the existing system for implementing the HRN EN 15085 requirements was assessed.
