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.

Low Hydrogen, Low Alloy Steel Group

Made for welding low alloy steels that require specific mechanical or chemical properties of one of these electrodes. Specifically for use in cryogenics, high temperature applications, and for x-ray quality requirements. These electrodes have Low Hydrogen “Fill-Freeze” operating characteristics similar to Jetweld LH-70.
