Process specification for S460ML steel beam in production

At present, the cutting thickness limit of laser cutting is 20 mm. However, it should be noted that oxygen will be added into the laser beam to cut 20 mm thick S460ML steel beam steel plate, which will form a thin oxide film on the cutting surface, which may affect the cutting quality, Therefore, attention should be paid to this point to avoid problems.

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, S460ML steel beam.
