ABSTRACT
Wire + Arc Additive Manufacturing (WAAM) is a metal additive manufacturing (AM) technique that enables the production of medium to large-scale near-net-shape structural parts with a high deposition rate. During this process, the filler wire is melted using current arc and deposited on a substrate or already solidified part to build up the structures in a layer-by-layer manner. This manufacturing method has recently attracted the attention of different industrial sectors such as aerospace, aviation, and shipbuilding due to its outstanding advantages such as lower buy-to-fly ratio and consequently lower cost, ability to repair operations as well as being environmentally friendly. In the current case study, the production of an ellipsoid-like structure with height of one meter using ER70S-6 steel wire is examined by the WAAM method. Determining the ideal parameters to produce this structure and corresponding tool path strategy, production of the part with the created tool path strategy and the verification of the part geometry with 3D scanning after the part production are discussed.
