Dynamic Analysis on Crbon Migration in Welded Joints of 12Cr2Mo1R and S30408 Dissimilar Steels
To understand the nature of carbon migration and diffusion in the welding process of 12Cr2Mo1R and S30408 dis-similar metals,the phenomenon of decarburization and carburization layer in the weld of the dissimilar steel after welding is confirmed in this paper through experiments;and then the diffusion behavior of carbon atoms in the welded joint is theoretical-ly analyzed.It lays a theoretical foundation for improving the quality of the welded joint of dissimilar steel.
