Precautions for Cheapest Stainless Steel So Flange.
1. In order to prevent inter-eye corrosion due to the heating of the flange cover, the welding current should not be too large, which is about 20% less than that of carbon steel electrodes, the arc should not be too long, and the interlayers are cooled quickly.
2. The electrode should be kept dry when used. The calcium-titanium type should be dried at 150°C for 1 hour, and the low-a hydrogen type should be dried at 200-250°C for 1 hour (do not repeat the drying many times, otherwise the coating is easy to crack and peel off), prevent The electrode coating sticks to oil and other dirt, so as not to increase the carbon content of the weld and affect the quality of the weldment.
3. When welding stainless steel flange pipe fittings, carbides are precipitated after repeated heating, which reduces corrosion resistance and mechanical properties.
4. The chromium stainless steel flange pipe fittings have a large hardening after welding, and the American standard flange is relatively large, which is prone to cracks. If the same type of chromium stainless steel electrode (G202, G207) is used for welding, preheating above 300°C and slow cooling at about 700°C after welding must be carried out. If the weldments cannot be post-weld heat treated, Cheapest Stainless Steel So Flange fitting electrodes (A107, A207) should be selected.
