Sažetak
The paper presents a set of findings important for a Wire Arc Additive Manufacturing using a welding robot. At the beginning an overview of additive manufacturing technologies for production of metal parts is presented. A special attention is set to wire arc additive manufacturing (WAAM) technologies. The advantage of WAAM compared to laser or electron beam technologies are lower investment and operational costs, while the disadvantage could be a lower dimensional accuracy. Due to higher productivity the WAAM technologies are more suitable for production of bigger parts. In this paper results study of WAAM using a welding robot and a CMT power source is presented. Thin walls have been cladded using G3Si1 welding wire. The microstructure and hardness of produced structures were measured and analysed. A research was done to determine the optimal welding parameters for production of thin walls with smooth surface. A SprutCAM software was used to make a code for 3D printing of sample part. It was find out that weld interpass temperature and workpiece to contact tip length play an important role in WAAM technologies.
