"WAAM process for metal block structure parts based on Mixed Heat Input" by Junyi Cui
Abstract Additive manufacturing based on robotic welding is used for the manufacturing of metal parts by applying an arc as a heat source and wire as feedstock. The process is known as Wire Arc Additive Manufacturing (WAAM). However, the current WAAM process has a limitation in fabricating block structure components with high geometry accuracy and consistent welding due to the process complexity and lack of appropriate process planning method. Furthermore, common defects such as voids, gaps and collapse decrease the mechanical properties of the final product. This thesis presents a novel proc...
