The electroslag welds were found to have a lower level of fracture toughness than implied from qualification tests . 人们发现电渣焊缝的断裂韧性较鉴定试验所给的结果要低。
The second crack is a crack originating at the groove weld toe of the column flange-girder flange connection . 第二种是产生于立柱翼缘与主梁翼缘连接处的坡口焊缝焊趾处的裂纹。
Cracks that have developed in the web at lateral connection plates have generally occurred because of intersecting welds . 腹板在水平连接板处出现裂纹，通常是由于有交叉焊缝。
Close examination of the plug welds showed the existence of herringbone patterns near the slag and voids in welds . 对塞焊焊缝的详细检查表明在焊渣及气孔附近，焊缝中存在着人字型裂纹。
Dye-penetrant and magneticparticle inspection techniques were used on the repaired and other 21 remaining original welds . 在已修补了的和其余21个原来的焊缝上进行了着色渗透和磁粉探伤工艺处理。
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。
