in order to prevent inter-eye corrosion due to flange heating, stainless steel flange welding current should not be too large, less than carbon steel electrode about 20%, the arc should not be too long, the interlayer fast cooling, to narrow welding channel is appropriate.
Stainless steel flange products are widely used reasons? Not stainless steel flange fittings welded, subject to repeated heating precipitation carbide, reducing corrosion resistance and mechanical properties. Product use a wide range of applications, nowadays has been applied by many industries. Today's products with the development of science and technology has been in the performance has been greatly improved. At present, many manufacturers produce sub-products, in order to use more safe and secure, before use must need to read the relevant instructions.
Some notes on the use of stainless steel flange:
1, in order to prevent inter-eye corrosion due to flange heating, stainless steel flange welding current should not be too large, less than carbon steel electrode about 20%, the arc should not be too long, the interlayer fast cooling, to narrow welding channel is appropriate.
2, the electrode should be kept dry when used, titanium calcium type should be dried at 150 ℃ for 1 hour, low a hydrogen type should be dried at 200-250 ℃ for 1 hour (can not be repeated drying, otherwise the flux skin is easy to crack and peel off), to prevent the electrode flux skin sticking to the oil and other dirt, so as not to lead to the weld to increase the carbon content and affect the quality of weldments.
