DN80 DN100 DN150 DN600 Flat Welding Stainless Steel Flange

Precautions for use

1. In order to prevent the corrosion between the eyes caused by the heating of the stainless steel flanges cover, the welding current should not be too large, about 20% less than the carbon steel electrode, the arc should not be too long, the interlayer should be cooled quickly, and the narrow weld bead is suitable.

2. The welding rod should be kept dry when it is used. The titanium calcium type should be dried at 150 ℃ for 1 hour, and the low-a hydrogen type should be dried at 200-250 ℃ for 1 hour (it cannot be repeatedly dried, otherwise the coating is easy to crack and peel off), so as to prevent the coating from sticking oil and other dirt, so as not to increase the carbon content in the weld and affect the quality of the weldment.

3. When welding stainless steel flanges pipe, carbide precipitates under repeated heating, which reduces the corrosion resistance and mechanical properties.

4. Stainless steel flanges fittings, butt welding stainless steel flanges electrode has good corrosion resistance and oxidation resistance, widely used in chemical industry, fertilizer, petroleum, medical machinery manufacturing.
