E6010 Cellulose Sodium Covered Electrode – All-Position, Vertical-Down Root-Pass Electrode
Designed for welding steel pipes of corresponding strength grades and for ship, bridge, and other structural welding, the JL-E6010 is a cellulose sodium-type acidic covered electrode. It uses DC reverse polarity and can perform all-position welding, including vertical-down welding. During vertical-down welding, the molten metal and slag do not flow downward; the arc force is strong and penetration is deep. For root-pass welding, it can achieve single-sided welding with double-sided formation and offers high welding efficiency.
Key Features
Cellulose Sodium Coating for Vertical-Down Welding
The cellulose sodium coating is specifically designed for vertical-down welding. It helps control the molten metal and slag, preventing them from flowing downward and supporting stable downward welding progress.
Deep Penetration and Strong Arc Force
The electrode provides strong arc force and deep penetration, which is beneficial for root passes and structural joints requiring reliable fusion.
Single-Sided Welding with Double-Sided Formation
In root-pass welding, it can achieve single-sided welding with double-sided formation, reducing the need for back gouging and improving overall efficiency.
High Welding Efficiency
Because it is suitable for vertical-down operation and root-pass single-sided welding, the electrode supports high-efficiency pipeline and structural welding.
DC Reverse Polarity and All-Position Capability
It operates on DC reverse polarity and can be used in all positions, including vertical-down welding, making it adaptable to pipeline, ship, and bridge fabrication.

Operating Notes
- Generally, the electrode does not require baking before welding. If it becomes damp, bake at 70–90°C for 1 hr before use.
- Before welding, remove rust, oil, moisture, and other impurities from the workpiece.
- During welding, the electrode should not be woven excessively; the arc height should be appropriate.
