Localized heating from the welding process and subsequent rapid cooling induces welding shrinkage stresses along weldbead 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 foundation of the future research of weld pool image processing and weldbead control was established.
为进一步进行熔池图像处理和焊缝成型控制的研究奠定了基础。

A method in which a data base and regression will be employed has been studied for predicting weldbead shape and selecting optimum welding parameters in arc welding processes.
