| Abstract: | The effect of yttrium oxide on microstructure, chemical composition and mechanical properties of weld metal was studied and the active mechanism of yttrium oxide was also discussed. The results show that yttrium oxide possess many good effects, such as refining micro-structure , changing the shape and distribution of inclusions, reducing the contents of sulfur as well as diffusion hydrogen and improving the impact toughness on weld metal. |

| Keywords: | rare earth oxide microstructure of weld metal low temperature impact toughness |
