摘要
耐候桥梁钢具备无需涂装即可应用于桥梁钢结构的优势,降低了钢结构的初始涂装费用和后期维护成本,避免了涂装过程对环境的负面影响.这种钢材具有强度高、耐蚀性优良以及对环境友好的特性.由于耐候桥梁钢在成分和使用方式上与常规钢种存在显著差异,国内外学者针对其展开了广泛研究.对近年来国内外关于耐候钢研发、制备与焊接技术的研究成果进行了梳理,包括各元素及环境对耐候钢耐蚀性影响的研究、耐候钢制备技术的开发、耐候钢力学性能与腐蚀疲劳的研究、耐候钢焊接工艺的开发以及耐候钢结构使用寿命的预测等方面.在此基础上,提出了针对我国实际应用场景,对耐候钢的设计、制造和焊接技术进行优化的建议,并对未来的研究工作进行了展望.
Abstract
Weathering bridge steel has the advantage of being applied to bridge steel structures without the need for painting,reducing the initial painting and later maintenance costs of steel structures,and avoiding the negative impact of the painting process on the environment.This type of steel has high strength,excel-lent corrosion resistance,and environmentally friendly characteristics.Due to significant differences in composition and usage between weathering bridge steel and conventional steel,scholars at home and abroad have conducted extensive research on it.The paper summarized the research results on the research and de-velopment,preparation,and welding technique of weathering steel at home and abroad in recent years,in-cluding the study of the influence of various elements and environments on the corrosion resistance of weath-ering steel,the development of weathering steel preparation technique,the study of mechanical properties and corrosion fatigue of weathering steel,the development of weathering steel welding process,and the pre-diction of the service life of weathering steel structures.On this basis,suggestions were put forward for opti-mizing the design,manufacturing,and welding technique of weathering steel for practical application sce-narios in China,and future research work was discussed.
