The weld joint is usually smooth and without porosity, which ensures the mechanical properties and corrosion resistance of the welded structure. This method is commonly used in the construction industry for joining steel plates, especially in bridges and other large-scale steel structures. The technology specification for cold zinc coating of steel structure bridge refers to the standard of cold zinc coating for steel structures, and provides the technic JTG D60-2004 General code for design of highway Bridges and Culverts JTG D64 YB/T 4365-2014 Steel Beam for Bridge Expansion Device
