E7018-1 Low Carbon Welding Electrodes

Composition: J506Fe-1 contains iron (Fe) powder and features a low-hydrogen potassium coating. The addition of iron powder can enhance the mechanical properties of the deposited metal.

Welding Positions: This electrode is suitable for welding work in all positions, including horizontal, vertical, and overhead positions. It offers versatility and flexibility, allowing for efficient welding in various orientations.

AC/DC Compatibility: J506Fe-1 can be used with both alternating current (AC) and direct current (DC) power sources. This makes it adaptable to different welding setups and equipment, providing convenience and ease of use.

Welding Performance: The electrode demonstrates good welding performance overall. It produces a smooth arc, which aids in precise control and manipulation of the weld pool. A smooth arc contributes to better weld quality

 

 

The product is applicable for welding important carbon steel structures and low alloy steel structures in marine engineering, shipbuilding and petrochemical industry.

1. Before welding, the welding electrode should be baked at 350℃ for 1 hour for ready use.

2. Impurities such as rust, oil stain and moisture must be cleared off of the work piece before welding.

3. Operating with short arc and narrow gap when weld
