By analyzing the part and fracture characteristic of sample , find the reason for this flaw is the choice of welding technology parameter is illogical ; welders don ' t grasp well the fibrin electrode ' s characteristics which distinguish with other low hydrogen electrodes , and usage isn ' t reasonable or operation isn ' t skilled 通过分析试样的取样部位和刻槽锤断试样断口的特点,发现产生缺陷的原因是焊接工艺参数选择不合理;焊工未能很好地掌握纤维素焊条与其他低氢型焊条相区别的特性,运条不合理或操作手法不熟练。
