Localized heating from the welding process and subsequent rapid cooling induces welding shrinkage stresses along weld bead during welding thin-wall plate and causes structural buckling distortions.
在薄板焊接中，由于局部加热和迅速冷却产生了沿焊缝方向的焊接收缩应力，而导致焊接薄板发生屈曲变形。

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。

In present paper, the form and mechanism of formation of out-of-plane distortion during bead-on-plate welding was studied by thermal clastic analysis with introduction of dummy element and experiment.
