Inclusion Morphology in Submerged Arc Weld Metal Using the Fluxes of the System (CaO)-MnO-SiO_2

Abstract

Inclusion morphology in SAW metal using the several fluxes of the system (CaO)-MnO-SiO_2 was investigated with SEM observation and X-ray microanalysis. Almost all inclusions were identified as manganosilicate and only a silicate containing sulphur was found out. It was suggested that these inclusions are originated in the redox equilibrium of manganese and silicon and manganese content in inclusion is not so changeable and richer than that of silicon. However, further investigations, especially on inclusion morphology in weld metal with fluxless welding process, are necessitated in order to certify these suggestions.
