Abstract This paper presents a general view of the technology intended for manufacturing of machine metal structural parts from a computer generated CAD drawings using an electric arc and filler wire. The proposed approach would make an alternative method of producing metal structures, with the benefit of large part size and high deposition rates. Concerned aspects that contribute to the geometry and structure of a finished part are observed. The welding inverter determines the arc energy and the deposition rate; therefore the differences between gas metal and gas tungsten arc welding are shown. Alongside the arc energy, factors like shielding gas type and torch angle contribute significantly to the size and shape of a bead. The general examination of the process of metal buildup is made using computer generated part geometry. In order to use a built part, it is very important to create a solid bond without any impurities. For testing purposes a small positioning apparatus is developed. This apparatus enables three axial movements to establish simple beads, besides an isolated environment and visibility of the process are provided.
