摘要
为了提高脉冲激光焊焊缝形状模型的可靠性和精度 ,引入了BP神经网络建模的方法 ,并通过脉冲激光焊焊接 10Mn镀镍板的实例建立了焊缝形状预测模型 ,经验证 ,预测值与实际值非常接近 ,精度很高 ,显示了该模型具有可行性和实用性。
BP neutral network is used to improve the dependabil it y and precision of welding line shapes model of pulsed laser welding.According t o the example that 10Mn steel plate is welded using pulsed laser welding,a weld ing line shapes forecasting model is set up.Verification shows forecasting value s and factual surveying value are almost identical,and the precision is high.Th e result shows this model is to be feasible and practicable.
