Abstract: The gradient coatings are prepared by use of plasma arc welding on the ZGMnl3 and U71Mn steels respectively, then, are welded together by use of flash welding. The separation of carbide and the formation of liquid crack are impeded in HAZ of ZGMnl3 steel. At the mean time, no martensite microstructure exists in HAZ of U71Mn steel. The technology of plasma arc welding combining flash welding is a effective technology for welding the ZGMnl3 steel crossing and U71Mn rail steel.
