Abstract
The welding of carbon steel for boiler structures poses significant challenges that remain an open problem for researchers. Welded joints in boiler applications are subjected to harsh conditions involving exposure to both fire and water environments, complicating material sustainability. This study focuses on the unique challenges arising from the interaction of welds with chloride-rich environments. The combustion of fuel and the presence of chloride in the aqueous zone are particularly influential factors, as highlighted by research on fire side columns. The weld zone experiences severe deterioration, resulting in substantial material loss. To address this issue, the current research involved subjecting the weld material to a chloride environment, with a comprehensive evaluation of the weldment's behaviour through electrochemical corrosion studies. Material characteristics were further analysed using electron microscopy, EDS spectra, and X-ray diffractometry. The corrosion results form the basis for recommendations and suggestions aimed at enhancing the resilience of weldments in carbon steel boiler structures, offering valuable insights for the improvement of material performance in challenging operational conditions.
