Optimization of Ultrasonic welding process using Imperialist Competitive Algorithm

In this paper Imperialist Competitive Algorithm (ICA) is applied to determine the optimum welding conditions that maximize the strength of joints produced by ultrasonic welding. Imperialist Competitive Algorithm is inspired by imperialistic competition mechanism and has shown some advantages such as simplicity, accuracy, and time saving in comparison with evolutionary algorithms. A case study from literature is presented to show the effectiveness of the proposed algorithm. In this regard, the imperialist competitive algorithm is utilized to predict weld strength by incorporating process parameters such as pressure, weld time and amplitude in ultrasonic welding process. The numerical results reveal that ICA can find optimum welding condition with higher accuracy in less computational time when compared to conventional Genetic Algorithm (GA).
