Analysis demonstrates effects of arc length and dynamics correction on weld overlay dimensions, highlighting their significance.
Wire Arc Additive Manufacturing (WAAM) is an arc-based additive manufacturing process used for the layer-wise fabrication of metallic components. The used process parameters significantly affect process stability, deposition quality, and surface integrity of the manufactured parts. Welding power source manufacturers allow some of the process parameters to be corrected, but they do not quantify these corrections in more detail. The objective of this study is to apply the Design of Experiments (DOE) methodology to assess the effect of selected process parameters such as arc length and arc dynamics on the geometrical features of the deposited layers, specifically bead height, bead width and deposition bead angle.
