摘要
在冷焊条件下,对U75V(PD3)钢轨采用以J557焊条为过渡层、贝氏体焊条(JD-937)为堆焊层的工艺方法进行焊修。分析堆焊层、热影响区、熔合线的组织,确定该焊修方式的可靠性,为实际过程中的修复操作提供依据。
It is research on repairing U75V（PD3） rail by welding in the cold weld condition with J557 welding rode as transition layer, and JD-937 （bainite welding rode） as overlaying welding.According to analyze structure of overlaying welding,heat affected zone and weld junction, we can ascertain the reliability of this repair welding method, which supplies the evidence of practice.
