      • Abstract
    • At first, H309L welding wire was welded on the groove of 13MnNiMoNbR steel plate by overlaying, then 13MnNiMoNbR and 00Cr19Ni10 steel plates were connected with H308L filler wire. Microstructure and hardness of the dissimilar steel welded joint were analyzed. The results show that coarse ferrite grain appeared nearby fusion line of 13MnNiMoNbR steel plate, namely decarburized layer. However, the black and fine carbides precipitated in fusion line of austenite surfacing layer of H309L weld beam. The microhardness obviously increased because of carbide precipitation or solution carbon in recarburized layer of H309L weld beam.
