weld bead

基本解释

Thiscondition can occur in any weld bead depression, but it is more likely to occur in the end of abead, especially a tack weld .
该情况可能发生在任何焊珠凹陷中，但其最可能发生在焊珠的末端，特别是点焊。
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。
