The E7010 welding rod is a high cellulose, sodium-coated electrode designed to deliver deep penetration and a forceful arc for all-position welding. Known for its excellent performance in pipeline welding and heavy structural steel fabrication, it offers strong fusion and superior slag removal.
This electrode is highly regarded for welding root passes on thick sections, pressure vessels, and piping where quality and strength are critical. The fast-freezing slag and stable arc provide ease of use in demanding field conditions and out-of-position welds.
Key Features
-
Deep Penetration: Powerful spray arc suitable for root passes on thick steel and pipe
-
All-Position Welding: Flat, horizontal, vertical (up/down), and overhead capabilities
-
Fast Freeze Slag: Thin, easily removed slag for cleaner welds
-
High Cellulose Flux: Provides excellent weld pool protection on dirty or rusty metal
-
DC Electrode Positive (DCEP): Requires DC+ polarity for optimal welding performance
-
High Deposition Efficiency: Enhanced productivity with iron powder in coating
Typical Applications
-
Oil & gas pipelines and pressure vessels
-
Structural steel construction including bridges and heavy frames
-
Shipbuilding and offshore platforms
-
Maintenance and repair of heavy machinery
-
Multi-pass welding requiring strong root penetration
