AWS E7018 is a kind of carbon steel electrode with iron powder low-hydrogen potassium type coating. AC/DC. The deposition efficiency can be improved due to the iron powder in the coating. It has stable arc, fewer spatters, good slag detachability and excellent welding performance. The deposited metal has excellent mechanical properties. All-position welding.

Instruction
①The electrodes must be baked under about 350℃ for an hour before welding, and used as soon as backing is completed.
②The stains on the weldments, such as rust, oil stains, moisture, etc., must be cleared away before welding.
③When welding, short arc must be used and stringer bead is suitable.
