Through the PCA of6welding parameters(wire feed rate,wire extension,welding speed,gas flow,welding voltage and welding current),4main factors were extracted to form the new training samples. The output results of ANN are satisfied.
以大电流MAG焊熔宽控制为例,通过对6个焊接过程参数(送丝速度、干伸长、焊接速度、气体流量、焊接电压及焊接电流)进行主成分分析,提取出影响熔宽的4个主要因素,形成新的训练样本集,送入神经网络进行计算,输出结果令人满意。
