Weather resistant steel plate requires special welding materials and processes when welding, and the oxidation rate of the welding point is the same as that of weather resistant steel plate. Although ordinary welding rods can also weld weather resistant steel plate, but the life of the welding is lower than that of the weather resistant steel plate.
Therefore, attention should be paid to the selection of special electrodes with weather-resistant toughening components and strength matching. In addition, weather resistant steel plate is not stainless steel. If there is water in the recesses of the weather resistant steel plate, the corrosion rate will be faster. Attention should be paid to the drainage treatment during construction, and weather resistant steel plate is very sensitive to salt-rich air conditions. In this case, the surface coating may not prevent further internal oxidation.
In the processing of weather resistant steel plate, the surface temperature of weather resistant steel workpieces is too high (more than 35 degrees) and too low (less than 5 degrees), high temperature exposure will have a bad influence on the rust effect, especially for coating rust inhibitors. When welding weather resistant steel workpieces, avoid construction under the above conditions.
