Product Description

 

Basic Carbon steelelectrodes
E7018 FeAccording with GB E5018
Introduction: 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. lt has stable arc,
fewer spatters, good slarg detachability and excellent welding performance.
The deposited metal has excellent mechanical properties.All-position welding.

Applications: Used for welding carbon steel and low-alloy steel structures,
such as 16Mn,etc.

Instructions:
1.The electrodes must be baked under 300~350C for an hour
before welding and used as soon as baking is completed.
2.The stains on the weld, such as rust, oil stains, moisture, etc.,
must be cleared away before welding.
3.When welding, short arc must be used and stringer bead is suitable
