J506Fe Welding Electrode

J506Fe is a carbon steel welding rod with iron powder and low hydrogen potassium coating, which can be used for both AC and DC. Since the coating contains iron powder, the welding efficiency can be improved. The arc is stable, less spatter, easy to remove slag, good process performance, good mechanical properties of deposited metal, and can be welded in all positions.

Features:

Usage:

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

Precautions:

⒈Before welding, the electrode must be baked at 350-380℃ for 1 hour and can be used immediately after baking.

⒉ Before welding, impurities such as rust, oil, moisture, etc. must be removed from the weldment.

⒊Short arc operation must be used during welding, and the swing range should not be too large. A narrow weld bead is suitable. In order to prevent the arc pores from being generated, an arc plate should be used to start the arc or the arc return method should be used for welding.
