Three proprietary high strength, low alloy steels and a high strength alloy steel were welded without a pre or post heat treatment with low hydrogen, iron powder coated electrodes of appropriate physical properties. Tensile and bend tests performed upon sample weldments indicated that they exhibited properties very similar to those for the base plate and that there were no indications of brittleness, notch sensitivity, underbead cracking, lack of fusion, hot cracking, undercutting, or crater cracking.
