Abstract

Unutar diplomskog rada iznesena je tematika aditivne proizvodnje električnim lukom i žicom. Rad je podijeljen na dva dijela, teorijski i eksperimentalni.
Teorijski dio rada obuhvaća osnovne teorijske postavke aditivne proizvodnje, različitih proizvodnih postupaka zavarivanja ovom tehnologijom te različitih parametara teksture površine.
Unutar eksperimentalnog dijela rada promatran je omjer brzine žice i brzine zavarivanja u odnosu na brzinu zavarivanja. Pomoću navedene tehnologije izrađeno je 9 zidova, od kojih su napravljeni uzorci na kojima su ispitivane njihove geometrijske značajke, makrostruktura te osnovna mehanička svojstva.
Naposljetku je dan zaključak.

Abstract (english)

Within the final thesis the topic of additive production with electric arc and wire is presented. The paper is divided into two parts, theoretical and experimental.
The theoretical part of the paper covers the basic theoretical assumptions of additive manufacturing, different welding production processes with this technology, and different surface texture parameters.
Within the experimental part of the paper, the ratio of wire feed speed and welding velocity to welding velocity was observed. With the mentioned technology 9 walls were made, of which samples were made and their geometrical characteristics, macrostructure and basic mechanical properties were examined.
Finally, a conclusion is given.
