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 indicate membrane permeability and cooling rate are main factors that affect the cell shrinkage.
计算结果表明，膜的渗透性和冷却速率是影响细胞体积收缩的主要因素。
