Abstract:
This article has studied the microstructure and hardness under the different intensity match the Nb-Cr X80 steel of SMAW joint,the results indicated that under different intensity match the filling pass microstructure through the following weld bead heat treatment,has broken the welded joint column crystals shape,weld joint microstructure is the acicular ferrite;coarse-grained zone microstructure is granular bainite+board ferrite banding.The cap weld microstructure is acicular ferrite;coarse-grained zone microstructure is board ferrite banding+granular bainite.The cap welded joint does not look like the root pass and the fill pass receives the heat treatment of the following bead,the high hardness microstructure of ferrite and the granular bainite increase obviously,caused hardness of the cap allover big.
