Abstract

U ovom diplomskom radu obrađen je postupak aditivne proizvodnje električnim lukom i žicom (eng. WAAM – Wire and Arc Additive Manufacturing).

U teorijskom dijelu obrađena je aditivna proizvodnja od povijesnog razvoja preko problematike sve do mogućnosti optimizacije procesa.

U eksperimentalnom dijelu opisana je oprema za zavarivanje i materijal koji je korišten pri izradi zidova. Zavarivanje zidova provedeno je robotom Almega OTC AX V6 s MAG postupkom u Laboratoriju za zavarivanje. Izrađena su 4 zida od legure Inconel 625 jednakim parametrima zavarivanja, ali korištenjem drugačije mješavine zaštitnih plinova za svaki zid. Dobiveni zidovi su izrezani i pripremljeni za nerazorna i razorna ispitivanja . Analizirani su dobiveni podaci te su doneseni zaključci o utjecaju zaštitnih plinova na svojstva zavara.

Abstract (english)

This thesis describes process of Wire and Arc Additive Manufacturing (WAAM), by means of a theoretical and experimental part.

In theoretical part an overview is given from historical development and process problems to process optimization.

Likewise in experimental part welding equipment and applied materials for welding walls are described. Walls weldnig was preformed with robot Almega OTC AX V6 with MAG in Laboratory for welding. Four walls were built from Inconel 625 alloy with same welding parameters, but using different mixtures of shielding gases. Furthermore , welded walls were cut and prepared for destructive and nondestructive testing . The data was analyzed and conclusions were made on the effect of different shielding gases had on weld metal properties.
