Abstract
U teorijskom djelu rada opisana je općenito aditivna proizvodnja, a nakon toga opisana je aditivna proizvodnja električnim lukom i žicom, skraćeno WAAM. Kako se u eksperimentalnom djelu koristio dupleks čelik, isti je također opisan u teorijskom djelu rada. Dan je opis te vrste čelika, njihova zavarljivost, korozijska postojanost te opća svojstva. Kako se kod WAAM proizvodnje koristi električni luk i žica kao dodatni materijal, opisani su postupci MIG/MAG zavarivanja s posebnim naglaskom na modificiranu inačicu – coldArc. U eksperimentalnom dijelu rada ispitana su površinska svojstva i određeni su parametri teksture površine uzorka izrađenog WAAM postupkom. Tijekom izrade uzoraka WAAM postupkom, ispitivana je dinamička karakteristika izvora struje u svrhu detaljnog promatranja ponašanja električnog luka tijekom zavarivanja, odnosno pratile su se promjene napona i struje tijekom formiranja i odvajanja rastaljene kapljice metala. Također, mjerila se visina nastalog zida kao i količina utrošene žice nakon dobivene predefinirane visine zida.
Abstract (english)
Presented work consists of two parts, theoretical and experimental. In the theoretical part, additive manufacturing is generally described after which wire and arc additive manufacturing is presented, in short WAAM. As the dupleks stainless steel was used in the experiment, the same was described in the theoretical part of the paper. General discription was given, as well as their weldability, corrosion resistance and general properties. Since WAAM production uses electric arc and wire as an additive, the MIG/MAG welding procedures were described with special emphasis on the modified version – coldArc. In the experimental part, on the samples made by WAAM, the surface properties were examined and sufrace texture parameters were determined. During the production of samples with the WAAM method, the dynamics of the current source were studied for the purpose of a detailed observation of the electric arc behavior during the welding process, ie changes in voltage and current were observed during the formation and separation of molten metal droplets. Also, the hight of the wall was also measured to see its grow rate (mm/1 pass), and to determine how much of additional material (metal wire) was used to create a wall of predefined height (85 mm).
