Esmacher, M J

Five case histories are presented on the effect of residual stresses (from fabrication or welding) on the waterside corrosion performance of carbon steel boiler tubing. Specifically, cases are reviewed in which tube swaging or tube bending operations (producing high forming stresses in deformed zones) resulted in the formation of stress-enhanced corrosion cells. In addition, the phenomenon of accelerated corrosion in welded support zones, membrane-welded panel sections, and weld-repaired areas is discussed.
