| Abstract Scope |
Wire Arc Additive Manufacturing (WAAM) is an additive manufacturing process based on robotic arc welding that enables the flexible, tool-less production of large-scale metal components. WAAM of aluminum alloys is particularly challenging due to their low melting temperature and high thermal conductivity, which result in a small process window. In this work, the processing of the cast alloy AlSi10Mg (EN AW-4046) by WAAM was investigated. For this purpose, a basic parameter development for WAAM of Al 4046 was carried out. Consecutively, first simple thin-walled geometries were built and analyzed regarding their mechanical properties, porosity, and surface properties. By adjusting the parameters, correlations between weld settings, path planning and the resulting properties have been identified. Furthermore, it was observed that the process tends to be sensitive to wire quality, which can be compensated by increasing the energy input. |
