Wire Arc Additive Manufacturing of Pelton Wheel Bucket

Wire and arc additive manufacturing (WAAM) is used for building medium- to large-sized components without using any support structures and also has a low buy-to-fly ratio compared to other additive manufacturing techniques. This study mainly focuses on the process planning in WAAM, which mainly requires CAD modelling software, slicing software, and a programming tool for tool path generation to build complex components. Pelton wheel bucket is manufactured with the developed methodology, which is used in hydraulic turbines for power generation. The proposed methodology can be used to build complex components in WAAM without using commercially available 3D printing software.
