Abstract Scope |
This study uses a Robot Operating System 2 (ROS 2) in-situ monitoring framework to capture data in real-time during arc-DED deposition. Finite Element Analysis (FEA) has been an instrumental tool in the study of wire-arc directed energy deposition (arc-DED) due to the insight it provides into the complex theromechanical processes underlying additive welding. FEA is limited by the requirement of input parameters such as weld bead geometry, thermal energy, and path of deposition. Measured data from the ROS 2 framework is then compared against FEA simulations to inform interlayer dwell time. This comparison is provided by both machine learning models and deterministic statistical models. Both types of models are then evaluated for their suitability in FEA-informed arc-DED feedback control. These simple models provide a basis for integrating FEA data into real-time arc-DED depositions and a framework for using faster FEA solvers for on-demand analysis during deposition. |
