| Abstract: | The flash welding technology of 45Si2Cr reinforced bar and its effect on the metallographic structure wcre studied in this paper. The results show that the coarse Widmanstattcn structure and microstructure defects can be eliminated by raising secondary voltage and enlarging upset allowance during welding process, and the mechanical requirements are satisfied. |
