Weathering steel plate for welding structure is made by adding metal materials such as chromium, molybdenum, titanium and vanadium to ordinary molten steel. The addition of these materials can form a protective film on the steel surface, which can resist weathering corrosion for a long time. The advantages of weathering steel plate for welding structure: It has very good welding performance and weather resistance, and is widely used in railways, bridges and other areas that need to be exposed to the atmosphere for a long time. Disadvantages of weathering steel plate for welded structure: It has very high requirements on the production process, and the poorer technology can not produce good weathering steel plate, 1.8974 steel for large truss truck boom.
