塞焊

不锈钢车体的主要焊接形式有点焊、环焊、塞焊等，焊接部位存在较大的应力集中，容易发生疲劳破坏。

运用有限元方法，对大型客车车身薄板结构焊接时采用的电铆焊、连续焊、断续焊及塞焊的残余应力进行了热-弹塑性数值模拟。

The dynamic welding residual stresses by plug welds , continuous welds and intermittent welds in sheet structure were simulated and analyzed by using thermal elastic-plastic finite element method .

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。裂缝中封存有焊药是强度不足或断裂的主要原因。

Thus the fracture likely initiated from fatigue sharpened cracks originating from slag and void in the plug welds . Flux entrapped in the joints is the principal cause of low strength or failure .
