A022 Stainless Steel Welding Electrode
GB/T 983 E316L-16 AWS A5.4 E316L-16 ISO 3581-A-E (19 12 3 L) R 3 2 ISO 3581-B-ES 316L-16
Suitable for welding 022Cr17Ni12Mo2 stainless steel structures, chromium stainless steel that cannot undergo post-weld heat treatment, clad steel, and dissimilar steels.
An ultra-low carbon Cr18Ni12Mo2 stainless steel electrode with a rutile-type coating. It offers excellent welding process performance, with a coating resistant to reddening and cracking, along with good corrosion resistance, heat resistance, crack resistance, and porosity resistance.
AC, DC reverse polarity (AC, DC?), with DC reverse polarity recommended.

1. Drying requirement: Electrodes must be baked at 300°C for 1 hour before use and used immediately after baking.
2. When using AC welding, spatter is higher, the coating is prone to reddening, and penetration is shallower. Therefore, DC reverse polarity welding is recommended.
3. Use low current and short arc welding as much as possible during welding, with minimal weaving.
