Materials Science Aspects of Weld Corrosion
Abstract
Corrosion is an environmentally assisted damage that professionals face daily, particularly with welded structures. Fusion welds result from solidification and solid-state transformations induced by well-localized thermal cycles. A fusion weld joint inherently exhibits an irregular surface as well as gradients in chemical composition, microstructure, properties and residual stress, depending upon process parameters and part geometry. This article analyzes the roles of surface topography, alloy chemical compositional variation, hydrogen distribution, and stress on weld corrosion.
