Performance Comparison Advantage: Compared with E7016 welding electrodes, E7018 contains more iron (Fe) element, resulting in higher welding efficiency and shorter cycle time for batch operations.
III. Product Performance Features
Excellent Process Performance: The coating adopts an alkaline + iron powder formula, ensuring stable arc, low spatter, and reduced difficulty in subsequent cleaning. The slag has good fluidity and is easy to remove, minimizing welding defects.
Superior Weld Quality: The weld formation is aesthetically pleasing with smooth and uniform weld beads. The deposited metal has excellent low-temperature toughness and crack resistance, making it suitable for low-temperature environments and high-stress working conditions.
Wide Application Scope: Supports all-position welding and is suitable for welding carbon steel, low-alloy steel, and shipbuilding ABDE grade steel, meeting various industrial needs.
IV. Application Fields
Special Equipment: Boilers, pressure vessels (welding of pressure-bearing components to ensure safe operation)
Infrastructure Projects: Connection of bridge steel structures (crack resistance and durability adapt to complex outdoor environments)
Pipes and Factories: Pipeline laying, construction of large steel structure factories (the all-position welding feature enhances construction flexibility)
