E7018 welding electrode

GB：E5018
 AWS：E7018
 Applications：Used for welding carbon steel and low-alloy steel structures, such as 16Mn, etc.
  

J506Fe

According with GB E5018
 Corresponding with AWS E7018

Introduction: J506Fe 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.

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

Instructions:
1.The electrodes must be baked under 300~350℃ 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.
