Which 70 KSI electrode is known for being both iron powder and low hydrogen?

The 7018 electrode is specifically designed to be both low hydrogen and contain iron powder. The composition of the 7018 electrode allows for improved weld deposition rates and greater overall quality in the welds made with it. Being low hydrogen, it is effective in preventing issues such as cracking, especially in high-strength steels. The inclusion of iron powder enhances its ability to improve fluidity and increase penetration, making it particularly suitable for structural welding applications.

This characteristic of the 7018 electrode makes it ideal for various welding situations where strength and reliability are critical, aligning with the requirements set forth in the Structural Welding Code.
