Abstract

U završnom radu obrađena je tema optimizacije aditivne proizvodnje električnim lukom i žicom pri izradi zida u nadglavnom položaju (PE). Rad se sastoji od teorijskog i eksperimentalnog dijela.

U teorijskom dijelu rada ukratko su opisani pojmovi poput povijesti, prednosti, nedostatci i primjene aditivne proizvodnje električnim lukom i žicom (engl. Wire + arc additive manufacturing (WAAM)). Navedeni su najčešći postupci zavarivanja koji se za tu tehnologiju koriste, a MAG postupak je detaljno objašnjen. Na kraju teorijskog dijela opisana je problematika zavarivanja u prisilnim položajima uz naglasak na nadglavni položaj zavarivanja.

U eksperimentalnom dijelu izrađen je zid aditivnom proizvodnjom električnim lukom i žicom u nadglavnom položaju. Dobiveni zid je izrezan i pripremljen za ispitivanja. Dobiveni podaci su analizirani i komentirani.

Abstract (english)

This thesis describes the optimisation of Wire and Arc Additive Manufacturing (WAAM) on wall fabrication in overhead position (PE). The thesis consists of theoretical and experimental part.

In theoretical part the terms like history, advantages, shortcomings and applications of WAAM are briefly described. The most common welding procedures used for this technology are listed and the MAG procedure is explained in detail. At the end of the theoretical part, the problem of welding in forced positions is described, with and emphasis on the overhead position of welding.

In the experimental part, the wall was made by WAAM in overhead position. The resulting wall was cut and prepared for testing. The obtained data was analyzed and commented.
