With SMAW method, the surfaces of A3 and 45 steel were welded by using the series of CHR electrode, and the microstructure and performance of surfacingwelding layer metal were analyzed.
Surfacing process is conducted on the substrate of steel A3 by shielded metal arc welding process using electrode CHR322 under different welding current conditions.
