The effect of weld chemistry on the oxidation of Alloy 82 dissimilar metal welds
Source abstract
Abstract
Alloy 82 dissimilar weld joints between carbon steel and Alloy 600 were exposed to a simulated primary water environment consisting of hydrogenated steam at 480 °C and 1 bar. Dilution due to mixing from the parent materials to the weld was significant, particularly in the root where there was Fe enrichment (35 at.%) and Cr depletion (10 at.%). The heterogeneous composition of the weld from root to crown resulted in differences with respect to surface versus internal oxidation. A Fe-rich surface oxide formed on the weld root which may help to prevent embrittlement and SCC by internal intergranular oxidation.
