| Abstract: | Firstly,the wet heating treatment accelerating corrosion was used to obtain corrosion specimens.Secondly,microscope was used to detect the depth of local corrosion.Finally,the depth of local corrosion and the surface corrosion damage ratio were used to describe the surface characteristics of the corrosion pit for welding.By the performance test of butt weld connection,the relationships between the corrosion damage ratio,the depth of local corrosion and the connection performance were obtained. |
