| Abstract: | 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 surfacing welding layer metal were analyzed. The results show that the microstructure and hardness of surfacing welding layer metal are influenced not only by the kind of electrode and welding procedure parameters, but also by the type, performance, quantity and distribution of hardening phase. |
