| Abstract: | A resitance weiding-flash weiding analag test of U_(71)Mn heavy rail steel made by AISC has been carried out in tester Gleebe-1500. Microstructures and mechanicar properties of HAZ are studied and influence of cooling transforma-tion behavior,cooling speed after welding and chemical compositions of U_(71) Mn heavy rail steel on weldability are analyzed. |
