Abstract (Croatian)

U teorijskom dijelu je analiziran prijenos metala MAG CBT postupkom te uspoređen s konvencionalnim prijenosom kratkim spojevima. Opisana je tehnologija aditivne proizvodnje električnim lukom i žicom (WAAM) te prikladnost pojedinih postupaka zavarivanja za realne aplikacije. U eksperimentalnom dijelu je razrađen plan pokusa za optimizaciju parametara MAG CBT postupka za aditivnu proizvodnju električnim lukom i žicom (WAAM). Određen je odgovarajući dodatni materijal i zaštitni plinovi te izračunati unosi topline. Napravljena su 2 uzorka istih parametara s različitim brzinama zavarivanja te je napravljena njihova usporedba. Ispitana su mehanička svojstva oba uzorka: statički vlačni pokus i mjerenje tvrdoće. Zatim je napravljena i makroanaliza. Na kraju je ocijenjena prikladnost definiranih parametara MAG CBT za aditivnu proizvodnju električnim lukom i žicom.

Abstract

The theoretical part analyzes the transfer of metal by the MAG CBT method and it is compared with the conventional transfer of short circuits. WAAM production technology and the suitability of some welding procedures for real applications are described and evaluated. In the experimental section, a plan for the optimization of parameters of the MAG CBT Procedure for Additive Electrical and Welding Procedure (WAAM) was elaborated. Appropriate additional material and protective gases have been determined and heat inputs are calculated. Two samples of the same parameters with different welding speeds were made and comparied by their mechanical properties. The mechanical properties of both samples were examined: static tensile test and hardness measurement. Thereafter, another test for macro analysis was carried out. Finally, the suitability of the defined parameters MAG CBT was assessed for the additive production of electric arc and wire.
