Tensile, Hardness, XRD and Surface Vonmises Stress of 316 L Stainless Steel Built by Wire Arc Additive Manufacturing (WAAM)
Keywords:Wire and arc additive manufacturing, 316L Stainless Steel , Comsol software
Wire arc additive manufacturing (WAAM) is a popular wire feed additive manufacturing technology that creates components through the deposition of material layer-by-layer. WAAM has become a promising alternative to conventional machining due to its high deposition rate, environmental friendliness, and cost-competitiveness. It is used to Fabricate complex shaped parts. The variable parameters are current, welding speed, shielding gas, and gas flow rate. This research fabricates 316 L stainless steel (WAAM plate) using a wire arc welding robot machine. Substrate and Side edges are removed using Microwire cut EDM, and the vertical milling machine finishes the surface. The tensile, hardness and X-ray Diffraction are compared with the standard 316 L stainless steel. The modelling and analysis of 316L stainless steel are carried out using COMSOL Multiphysics 5.3 software. It is concluded that the additive manufacturing of 316L stainless steel by wire and arc process is feasible.
