采用焊条电弧焊修复2FC-20分级机断裂螺旋轴,运用内镶轴套、设计塞焊孔等措施,正确选择焊接工艺参数,实施交叉对称反方向施焊,并利用钨极氩弧整形过渡区,取得了很好修复效果。
Welding rod arc welding was used to repair the fracture screw shaft of 2FC-20 classifier, the inner sleeve and the plug hole were designed to select the welding process parameters correctly. Cross-symmetry anti-direction welding was applied and the TIG welding transition zone , Made a very good repair effect.
