Optimization of Bead Geometry in Electron Beam Welding Process Using Imperialist Competitive Algorithm

This paper presents optimization of bead geometry in Electron Beam Welding (EBW) process using of Imperialist Competitive Algorithm (ICA). Minimization of the weld area is considered as objective. Generally, in welding process, weld bead geometry and weld quality are, in most parts, depend on welding parameters, thus the weld quality is usually measured in terms of weld bead geometry which that includes weld height, width and penetration. Therefore, in this study, an attempt was made to minimize the weld area, after satisfying the condition of maximum bead penetration using of Imperialist Competitive Algorithm. ICA has demonstrated excellent capabilities such as simplicity, accuracy, faster convergence and better global optimum achievement. The results of ICA were finally compared with the Genetic Algorithm (GA). The outcome shows the success of ICA in optimizing the weld bead geometry.
