Abstract: Welding of high manganese steel and high carbon steel is difficult because there are so many different between these steels such as chemical,physical and mechanical properties respectively.The welding property of high manganese steel and high carbon steel was examined through the study in paper Ⅰ and paper Ⅱ.By the microstructure analysis,SEM analysis and energy spectrum analysis of welded joint,the welding method of high manganese steel and high carbon steel was determined.The method supplies particulate welding technology.It is studied in the paperⅡfor welding the two kinds of steel directly or with intermediate layer between them.Then the best welding technology was worked out.
