摘　　要：采用YLS-10000光纤激光器对E36船用高强钢试板进行对接焊，在0．0～0．81mm间隙范围内每隔0．05mm进行一组正交试验，找到各间隙下合格焊缝所对应的焊接功率与送丝速度。采用BP神经网络对所得参数拟合，从而建立工艺模型，并通过验证性试验鉴定了模型的可靠性。YLS-10000 fiber laser was used on butt welding of E36 marine high strength steel sheet, and the appropriate welding power and wire feeding speed were found through orthogonal test under different clearances of 0.0mm-0.8mm and every other 0.05 ram. BP neural network was used to fit the parameters and establish the process model, and the reliability of the model was verified by verification experiment.
