The influence of heating of stainless steel flange cover

by:Mayer     2021-08-24
In order to prevent the corrosion between the eyes due to the heating of the stainless steel flange cover, the welding current should not be too large, which is about 20% less than that of the carbon steel electrode, the arc should not be too long, the interlayer cooling is fast, and the narrow welding bead is better. The stainless steel flange electrode should be kept dry when in use. 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. Prevent the electrode coating from sticking to oil and other dirt, so as not to increase the carbon content of the weld and affect the quality of the weldment.
