Abstract
Rad se sastoji od teorijskog i eksperimentalnog dijela. U teorijskom dijelu dan je pregled i opis strukture niza normi HRN EN 15085, gdje su detaljnije proučeni zahtjevi za proizvodnju zavarivanjem vezani za razinu klasifikacije proizvoda. Nadalje, odabrano je pet potencijalno kritičnih zavarenih spojeva grudne grede čiji su detalji konstrukcijskih rješenja analizirani. Uz to, opisane su pojedine obrade koje se mogu izvršiti nakon zavarivanja u svrhu poboljšanja eksploatacijskih značajki, kao i primjenjive metode nerazornih ispitivanja s obzirom na klasu zavara i razinu naprezanja grudne grede. U eksperimentalnom dijelu provedena je specifikacija zahtjeva proizvodnje za izradu zavarene konstrukcije grudne grede. Definirana je tehnologija zavarivanja grudne grede prema specificiranim i kvalificiranim postupcima zavarivanja. Provedene su određene metode nerazornih ispitivanja na odabranim zavarenim spojevima te su dana tražena izvješća. Shodno tome, predložene su radne probe čije su pozicije označene na određenim mjestima grudne grede. Zaključno, predložena je mogućnost poboljšanja vođenja sustava kvalitete prema zahtjevima norme HRN EN 15085.
Abstract (english)
The work consists of a theoretical and an experimental part. The theoretical part provides an overview and description of the structure of the series of standards HRN EN 15085, where the requirements for production by welding related to the classification level of products are examined in detail. Furthermore, five potentially critical welded joints of the chest beam are selected, and the details of their design solutions are analyzed. In addition, certain treatments that can be performed after welding to improve operational characteristics are described, as well as applicable non-destructive testing methods considering the weld class and the stress level of the chest beam. In the experimental part, the production requirements specification for the manufacturing of the welded chest beam structure is carried out. The welding technology for the chest beam is defined according to the specified and qualified welding procedures. Certain non-destructive testing methods were applied to the selected welded joints, and the required reports were provided. Consequently, production weld tests were proposed, and their positions were marked at specific locations on the chest beam. In conclusion, the possibility of improving the quality management system according to the requirements of the HRN EN 15085 standard was suggested.
