Abstract
In Wire Arc Additive Manufacturing (WAAM), weld beads are deposited layer-by-layer to form the final part. Thus, having geometrically non-uniform beads will lead to voids in the final printed part, which will significantly impact its overall quality and mechanical strength. The uniformity of beads depends on the proper choice of process parameters, namely the torch speed and wire feed rate. However, it is impossible to print all different combinations of these parameters to model the bead accurately, as printing them is expensive and time-consuming. Therefore, in this paper, we propose building a process map based on the probability that a weld bead is geometrically uniform using support vector machine. Experiments are carried out on the Bronze and Stainless Steel material datasets. The results show that the generated process map co-relates well with that of a manual quantization approach.
