Key Features of Welding Electrodes – Low Hydrogen

Superior Performance with AC and DC Current

Welding Electrodes – Low Hydrogen (E7018) work efficiently with both AC (Alternating Current) and DC (Direct Current) power sources. They operate well under electrode positive (EP) or electrode negative (EN) DC polarity. This versatility makes them suitable for various welding tasks.

Low Hydrogen Content for High-Quality Welds

E7018 electrodes contain low hydrogen, reducing the risk of hydrogen-induced cracking in welds. This ensures strong, reliable welds with minimal defects, making them ideal for high-strength steel applications where quality and safety are crucial.

Ideal for Structural Applications

E7018 is perfect for structural welding. It provides the necessary chemical properties for durable, strong welds in heavy-duty applications, including construction and industrial fabrication. This electrode meets the demands of welding in challenging environments where strength is a priority.

All-Position Welding Capability

E7018 rods perform well in all positions: flat, horizontal, vertical, and overhead. This makes them versatile for different welding setups, ensuring smooth arcs and stable welds even in difficult positions.

Suitable for Medium-Grade Carbon Steels

E7018 is ideal for welding medium-grade carbon steels without preheating. It also works well on cold-rolled steels that tend to exhibit excessive porosity with conventional electrodes. The low hydrogen content reduces porosity and produces cleaner, stronger welds.

Consistent and Stable Arc

E7018 produces a stable, smooth arc, which gives the welder better control over the weld pool. This consistency makes it easier to create precise, high-quality welds with fewer defects, saving time and reducing the need for rework.

Durability and Resistance to Cracking

The low hydrogen content and balanced alloy of E7018 help resist cracking. This makes the rod suitable for applications where the weld must withstand high stress, such as pressure vessels, bridges, and structural components.

Summary

E7018 low hydrogen welding electrodes ensure strong, crack-resistant, high-quality welds. Their ability to work with AC and DC current, along with their versatility in all welding positions, makes them ideal for structural and medium-grade carbon steel applications. These rods provide reliable, durable welds with minimal defects, even in challenging environments.
