Abstract (Croatian)

U teorijskom dijelu rada opisana je aditivna proizvodnja s posebnim osvrtom na proizvodnju čeličnih materijala postupkom aditivne proizvodnje električnim lukom i žicom (WAAM). Opisana su svojstva i zavarljivost dupleks čelika, a detaljnije je opisana njihova mikrostruktura. U eksperimentalnom dijelu rada ispitana su površinska svojstva i određeni parametri teksture površine uzorka izrađenog WAAM postupkom. Na uzorcima izrađenima WAAM postupkom ispitan je utjecaj parametara zavarivanja i sastava zaštitnog plina na kvalitetu površine i mikrostrukturu. Temeljem dobivenih rezultata utvrđena je optimalna tehnologija aditivne proizvodnje dupleks čelika električnim lukom i žicom.

Abstract

In the theoretical part, additive manufacturing is described with special refrence to the wire and arc manufacturing of steel materials. The properties and weldability of duplex stainless steels are described, and their microstructure is described in more details. In the experimental part, the surface properties of the wall produced with WAAM method were examined and height parameters were specified. On the samples of duplex stainless steel produced by wire and arc additive manufacturing the influence of the welding parameters and protective gas on the surface quality and microstructure was examined. Based on the obtained results, the optimum technology for wire and arc additive manufacturing of duplex stainless steels was established.
