2 mm~5 mm Sino Erli SS E309L Titanium calcium type coating welding electrode E309L-16/ISO 3581-B-ES 309L-16

E309L is an ultra-low carbon Cr23Ni13 stainless steel electrode with titanium calcium coating. It has excellent crack resistance. AC and DC dual purpose, capable of all-position welding
Commonly used for welding of stainless steel and other dissimilar steels, and also for welding of transition layers of petrochemical pressure vessels and other equipment

 Attention:

1. The electrode must be baked at 300°C for 1 hour before welding, and used as it is baked.
2. Try to use small current and short arc welding when welding.
3. The weldments must be cleaned of rust, oil stains, moisture and other impurities before welding.

4. Try to use small current and short arc when welding, and the swing width should not exceed 2.5 times the diameter.
