【摘要】 介绍了螺旋埋弧焊管焊缝余高的重要性、焊缝余高对焊缝力学性能的影响以及余高对螺旋埋弧焊管防腐的影响。该研究将神经网络用于建立螺旋埋弧焊管焊缝余高的预测模型。在构建网络预测模型的过程中,以焊接电流、电弧电压与焊接速度作为网络输入,以焊缝余高作为网络输出。对网络进行了训练,并对训练结果做了回归分析。为了检验网络的泛化能力,对网络进行了测试,结果显示所建立的网络是比较成功的。更多还原

【Abstract】 This article introduced weld reinforcement importance to SSAW pipe,effect of weld reinforcement to weld mechanical property and to SSAW pipe anti-corrosion.And then,used neural network to establish a prediction model for the weld reinforcement of SSAW pipe.It made welding current,arc voltage and welding speed as input of the network,the weld reinforcement as output.Finally it trained the network,and conducted regression analysis for training results.In order to verify thegeneralization ability of the network to test the network,the results showed that the establishment of the network is relatively successful.更多还原
