Abstract
The deposition rate is a critical parameter that has a significant influence in Wire Arc Additive Manufacturing (WAAM) of critical aerospace components made of AISI 410 Stainless steel. In this work, Taguchi parametric modeling for wire arc additive manufacturing is carried out using the input parameters of the welding current (WC), the travel speed of the nozzle (TSN), and the distance between the nozzle and the workpiece (DNW). Each factor is varied at 3 levels and the experiments are carried out based on Taguchi L9 orthogonal array. The response variable considered is the deposition rate (DR). Based on the results from experiments, the optimal combination of process parameters obtained is 140 A of welding current, 3mm/s of the travel speed of the nozzle, and 15 mm of distance between the nozzle and workpiece. The optimum deposition rate achieved is 8.545 g/s. The percentage of contribution of various factors is found to be TSN at 43.65% and WC at 16.6% and DNW at 4.9%.
