The welding parameters of CO2 welding iron, P-GMAW of iron and DP-GMAW of aluminum are long-step calibrated through a lot of tests.

通过大量工艺试验，对CO2焊钢、P - GMAW焊钢、DP - GMAW焊铝等工艺的焊接参数进行了大步距标定。

The results showed that the backside melting width can be predicted by the network model during P-GMAW bead welding the thin plate when the welding parameters were input variable.

结果表明，在P - GMAW薄板堆焊中，以焊接规范为输入变量，利用该网络模型能很好的预测背面熔宽。
