<p>U disertaciji je prikazan odabir rastvarača, veličine, vrste i udela čestica za aktivni premaz namenjen postizanju povećane dubine uvara na austenitnom nerđajućem čeliku pri zavarivanju netopljivom elektrodom u zaštiti inertnog gasa. Pored sastava aktivnog premaza, u disertaciji je izvršena optimizacija: geometrije elektrode, jačine struje i brzine zavarivanja. Nakon odabira perspektivnih tipova sastava premaza i parametara zavarivanja, na zavarenim uzorcima izvršena je karakterizacija mehaničkih osobina, hemijskog sastava i mikrostrukture.</p> / <p>In this doctoral thesis, the selection of solvent, size, type and the content of<br />oxide particles in activated flux aimed at increasing the penetration on<br />austenitic stainless steel in gas tungsten arc welding is presented. Besides<br />activated flux composition, the optimization of welding parameters such as<br />electrode geometry, welding current and welding speed was done. After the<br />selection of successful activated flux formulations and welding parameters,<br />the characterization of mechanical properties, chemical composition and<br />microstructure was determined.</p>
