Advances in Research and Development,Preparation,and Welding Technique of Weathering Bridge Steel
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.
