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。
These attachments were considered secondary components, so no weld quality control has been imposed on the groove weld splice . 这些附连件被看作是次要的部件，所以在这种坡口焊接中没有进行焊接质量控制。
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。
To evaluate fracture instability, the total sum of stresses due to residual welding or rolling stresses, dead load, and live loads must be considered . 计算断裂失稳性时，必须考虑焊接或轧制残余应力，恒载应力和活载应力之总和。
The forces that developed from the deformation in the cross-frame were primarily transmitted from the connection plate into the web by the upper pair of intermittent fillet welds . 因横向框架中的变形所发生的力最初由连接板通过较上面的一对间断贴角缝传入腹板中。
