Electron Beam Welding (EBW) was employed to join HY282 alloy. However, modeling and optimization of EBW of HY282 alloy have not been reported yet. In this study, a novel and robust approach has been proposed for the input-output modeling and optimization of EBW of HY282 alloy, using Artificial Neural Networks and metaheuristic algorithms. The output parameters were the Ultimate Tensile Stress (UTS) and Microhardness (MH). The present study implemented four ANN models trained using Genetic Algorithm (GA), Bonobo Optimizer (BO), Gray Wolf Optimizer (GWO), and Particle Swarm Optimization (PSO), respectively. Among these models, ANN trained by GWO was found to provide the best predictions for the EBW weld attributes, with an average absolute deviation of 2.8%. Further optimization of the ANN model to maximize the UTS, PSO yielded the highest UTS, around 849.7 MPa. Finally, confirmatory test results closely matched the simulated ones. |
