Abstract

Tema diplomskog rada je optimizacija tehnologije zavarivanja čelika S355J2+N i X5CrNi18-10 MAG postupkom zavarivanja. U teorijskom dijelu obrađena je zavarljivost nelegiranih te visokolegiranih čelika, zavarivanje raznorodnih čelika, unos topline potreban za zavarivanje te MAG postupak zavarivanja. Eksperimentalni dio rada obuhvaća provedbu zavarivanja nelegiranog S355J2+N i visokolegiranog X5CrNi18-10 čelika MAG postupkom. Na zavarenim uzorcima su provedena ispitivanja mikrostrukture i tvrdoće te doneseni određeni zaključci.

Abstract (english)

The topic of the thesis was the optimization of welding technology for S355J2+N and X5CrNi18-10 steels using the MAG welding process. The theoretical part covered the weldability of non-alloyed and high-alloyed steels, welding of dissimilar steels, heat input required for welding and the MAG welding process. The experimental part included conducting MAG welding of non-alloyed S355J2+N and high-alloyed X5CrNi18-10 steels. A series of tests were conducted on the butt-welded joints to evaluate their microstructure and hardness.
