Mild Steel Welding Electrode AWS E7018
E7018 is a low-hydrogen-potassium covered electrode is widely used for welding carbon steel and low-alloy steel. E7018 covered electrode belongs to alkaline covered electrode with low hydrogen content, so attention should be paid to moisture prevention and preheating during welding. DC reverse connection is required for alkaline covered electrode welding, and covered electrode should be dried before welding. Alkaline covered electrode is suitable for welding important structures, such as pressure vessels, bridges and other occasions that require high weld quality.

APPLICATIONS:
It is suitable for the welding of carbon steel and low alloy steel structure, such as Q345, an so on.
FEATURES:
E7018 is basic coated iron powder low potassium hydrogen type electrode. Both AC and DC can be used and can be all-position welding. It can reach excellent welding performance, good arc stiffness, little spatter, easy slag removal and good weld appearance, high deposition efficiency, and can reduce welding layers.

ATTENTION:
1. Electrode must be approved by 350-380℃ for 1 hour before welding, dry the electrode when use it.
2. The rust, oil, water and other impurities of the weld must be removed before welding.
3. Must use short arc welding, the swings should not be too large, narrow bead welding is appropriate.
4. To prevent producing arc porosity, arc plate should be adopted or use return method for arc welding.
