Additive manufacturing has gained a profound interest from the scientific community due to its economic benefits and the possibility to fabricate functional parts with complex geometrical structures using particularly any kind of material. Wire arc additive manufacturing is the cutting-edge additive manufacturing technology, which has a huge potential for industrial applications such as the production of real parts and their prototypes, maintenance, and repair operations. This article presents a study of the influence of process parameters on the deposition behavior of low-carbon low-alloy steel during the additive manufacturing process. The primary objective of the study is to identify the challenges and issues attributed to the utilization of this novel technology. During the experiments, the optimal process parameters were selected for the deposition of beads. The relationships between the process parameters and the bead geometry were determined. Adjustments of the parameters were made during the deposition of the walls consisting of a different number of layers. Once adjustments had been completed, more complex samples of square and cylinder geometric structures were deposited. After deposition, the common defects and their possible causes were identified, and recommendations for their elimination were given. At the end of the experiments, the quality of the samples obtained under these conditions and the available equipment was evaluated. Recommendations for improvement of the process are given and directions for future research are defined. |
