摘要
介绍了焊条加长,深孔补焊技术。通过焊接性分析、焊接试验、焊接工艺评定,确定了合理的焊接工艺参数;几台机车锅炉火箱内壁腐蚀坑的问题得到了解决,切实可行,取得了效果。
This article introduces how to lengthen the welding rod and the technique of repair-welding in a deep hole. By the welding analysis, the welding test and the assess of welding craft, the reasonable welding craft parameter can be fixed. So the problem of the corrosive pits in several locomotive boiler wall inside the firebox can be solved. It is practicable and takes good effect.
