【Abstract】 Artificial Neural Network (ANN) is used to develop the weld metal geometric model of deep penetration laser welding. A framework of expert system based ANN was also developed. Using the experimental data from Nd:YAG laser welding Monel 400, the relationship between the welding parameters and the weld metal geometry were studied. A method to optimize the welding parameters based on ANN model is introduced. The result shows that the ANN model could meet the high standard practical requirement.更多还原
