- All-position welding capability with easy slag removal and minimal spatter
- Outstanding mechanical properties and low-temperature impact toughness
- Excellent bead appearance and penetration for root pass welding
Typical Applications
- Medium carbon steel and low-alloy high-strength steel structures
- Pressure vessel and industrial boiler fabrication
- Shipbuilding and offshore oil platform construction
- Bridges, heavy machinery, and structural steel frameworks
- High-pressure pipeline welding and critical load-bearing joints
Welding Positions
- PA / PB / PC / PD / PE / PF
WARNING
- The electrodes must be re-dried at 350–380°C for 1 hour before welding.
- Rust, oil, moisture, and other contaminants must be removed from the weld area before welding.
