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.

用于锅炉结构的碳钢焊接提出了重大挑战，这对研究人员来说仍然是一个悬而未决的问题。锅炉应用中的焊接接头要承受恶劣的条件，包括暴露在火和水环境中，使材料的可持续性变得复杂。本研究重点关注焊缝与富含氯化物的环境相互作用所带来的独特挑战。正如对火侧柱的研究所强调的那样，燃料的燃烧和水区中氯化物的存在是特别有影响的因素。焊接区严重恶化，导致大量材料损失。为了解决这个问题，当前的研究涉及将焊接材料置于氯化物环境中，并通过电化学腐蚀研究对焊件的行为进行综合评估。使用电子显微镜、EDS 光谱和 X 射线衍射法进一步分析材料特性。腐蚀结果构成了旨在增强碳钢锅炉结构焊件弹性的建议和建议的基础，为在具有挑战性的操作条件下提高材料性能提供了宝贵的见解。
