Numerical Simulation of Flash Butt Welding of High Manganese Steel Crossing with Carbon Steel Rail

Abstract:

Article Preview

A flash butt welding model of a high manganese steel crossing was established using the thermal coupled finite element method (FEM). The model considers comprehensively the physical parameters of materials, which change with temperature, as well as the burning material caused by the splutter during welding process. The temperature field of the flash butt welding joint and the cooling curves of the high manganese steel crossing at various locations near the welding seam were simulated. Comparisons with actual welding specimens of high manganese steel crossing indicated that flash butt welding model of the high manganese steel crossing is reasonable, and the temperature field distribution near the welding seam after flash butt welding can thus be appropriately evaluated by the simulation results.
