【Abstract】 The optimal welding path should be able to minimize the general distortion and consequently improve product’s quality.In this paper,A thermo-mechanical model is developed to estimate welding distortion,and the genetic algorithm(GA)is applied to optimize the welding path.Finally,a welding path optimization process based on the suggested strategy is demonstrated.更多还原
