Thus the fracture likely initiated from fatigue sharpened cracks originating from slag and void in the plug welds . 因此，断裂可能是由于从塞焊焊缝内的焊渣和气孔外形成的尖锐的疲劳裂纹而产生的。
This consists for the most part in straightening up, cleaning, and, on thicker plates above 5/16 in vee-ing the edges . 主要是矫直，清选，对于厚度超过516英寸的金属板，还需将焊边做成V形坡口。
Some crack extension probably developed from the unfused section of the butt weld across the thickness of the stiffener during transport and erection . 有些裂纹可能在运输和安装过程中就从加劲肋对接焊未熔透处开始发展。
Cell connectors and terminal post burning must be done in such a manner that there is complete fusion of the post strap top and the cover lead bushing with the connector ring or terminal post . 连接条和接线柱的焊接必须使极柱顶部和盖子的铅衬套与连接条环口或接线柱完全熔焊牢固。
