GB/T 983 E309-15 EQUIVALENT NORM: AWS A5.4 E309-15


a.LY-E309-15 is a low hygrogen type welding electrode for stainless steel. The weld seam metal has excellent mechanical properties and shows good resistance to intergranular corrosion. b.DC is applied and the electrode should be contacted reversed polarity .It is used for all position welding with excellent performances:stable arc,small spatters,good appearance of weld.And also the welding electrode shows good heat-resistance character, not easy to turn red.


Suitable for welding stainless steel of similar types,or dissimilar steels as well as high Cr steels and high Mn steels.

a.Before welding,the welding electrodes should be baked at the temperature of 300 to 350℃ for one hour.
b.The stainless steel brush must be used to clean the weld seam,in order to avoid iron filings penetrating there to affect its quality.
