BASOWELD Unalloyed Basic Electrode 50 3.25x450mm 5.5kg E7018 Low Hydrogen Welding Rod

The BASOWELD Unalloyed Basic Electrode 50 is a premium low-hydrogen welding rod engineered for high-integrity welds on mild and low-alloy steels. Its basic coating delivers a smooth, stable arc with minimal spatter and easy slag removal, making it ideal for critical structural applications. With a 3.25 mm diameter and 450 mm length, this electrode offers excellent control in all positions except vertical down, ensuring strong, crack-resistant joints even at sub-zero temperatures.

Advantages

Low hydrogen content (<5 ml/100g) reduces the risk of hydrogen-induced cracking, while the basic coating provides excellent mechanical properties: tensile strength of 490 MPa, yield strength of 400 MPa, and 22% elongation. The electrode performs reliably on DC+ or AC, with an amperage range of 90-140 A for 3.25 mm rods. Its all-position capability (except vertical down) and easy slag detachability boost productivity in demanding welding tasks.

Recommendations

For best results, store electrodes in a dry, heated cabinet at 100-150°C to maintain low hydrogen levels. Re-dry at 300-350°C for 1-2 hours if exposed to moisture. Use DC+ for optimal arc stability and penetration, especially in out-of-position welding.
