AWS A5.1 E7018

EN ISO 2560-B-E4918A

Characteristics and Application

iron powder welding electrode E7018 is suitable for the welding of carbon steel and low alloy steel structure, such as Q345, an so on.

Features: It 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.

Notes on usage:

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.You 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.
