Chrome-nickel stainless steel welding electrodes Notes

Chrome-nickel stainless steel electrode has good corrosion resistance and oxidation resistance, widely used in chemical, fertilizer, petroleum, medical equipment manufacturing. Chrome-nickel Stainless Steel Electrode, carbide precipitation by repeated heating and reduce corrosion resistance and mechanical properties.
Chrome-nickel stainless steel skin with titanium calcium type drugs and low-hydrogen type. Titanium calcium type can be used for AC and DC, but AC welding penetration shallow and easy to redness, so as far as possible dc power supply. Diameter of 4.0 and below can be used for all position welding pieces, 5.0 and above for flat butt and fillet weld.
Electrodes should be used to keep dry, titanium calcium type shall be 150 ℃ drying 1 hour, low-hydrogen should be dried by 200-250 ℃ for 1 hour (can not be repeated drying, easy to crack and peel off the skin or drugs), drugs to prevent skin electrode viscous oil and other dirt, so as not to increase the carbon content of the weld and the resulting impact on the quality of weldments.
To prevent corrosion of heat generated between the eyes, the welding current is not too large, less than about 20% of carbon steel electrode, the arc should not be too long, rapid cooling layer to narrow weld appropriate.
