Low Hydrogen Group
For welding carbon and low alloy steels that require 70,000 psi tensile strength deposits. These low hydrogen electrodes can produce dense, x-ray quality welds with notch toughness properties. The E7018 electrodes have “Fill-Freeze” characteristics and the E7028 electrode has “Fast-Fill” characteristics.
