A flux cored, gas shielded arc welding electrode for depositing a weld metal with low diffusible hydrogen and having tensile strength greater than 90 Kpsi and a yield strength greater than 80 Kpsi. The electrode includes a nickel free steel sheath with a carbon content of less than 0.05% of the sheath and a core in the range of 13-17% of the electrode wherein the core includes primary alloy particles of iron, manganese, magnesium and nickel with a minor amount of secondary alloy particles of a silicon alloy and a boron alloy in a rutile based slag system. The nickel has a controlled amount in the general range of 1.0-2.0% by weight of the electrode and the rutile is 40-60% by weight of the core.
