Abstract

AM of the AlSi10Mg alloy has been explored in recent years and a thorough understanding of both macro-and microstructure of AM components is a necessity for control of their properties and applications. However, since various hatching strategies are employed, the end products will yield different structures. In the present work thin-walled containers were fabricated by an industrial AM-SLM system. These containers were built utilizing the "strip scanning" hatching strategy and their in-depth characterization was conducted. The components were sectioned and observed from all orthogonal planes to represent the macrostructure of the components at different locations and geometries with further emphasis on defect locations. In addition, Electron Beam Welding (EBW) was employed in joining the thin-walled containers showing the feasibility of EBW to overcome the size limitation issue. Weldability was improved by applying the conduction mode regime; at slower welding speeds, a higher quality weld metal (WM) with less porosity was obtained.
