Abstract
A mild steel flux-cored electrode is disclosed for use in arc welding mild and low alloy steels, which electrode complies with the specification of the American Welding Society (AWS A5.20-69) classification E70T-1. The electrode has an external diameter of 3/32" and includes a core that is contained within a mild steel sheath formed from a strip of approximately 0.012" in thickness and approximately 0.505" in width. The core constitutes approximately 45.0% of the weight of the electrode and includes as a major component iron powder having an apparent density of approximately 3 grams per cubic centimeter. The core also includes manganese and silicon in an approximate ratio of 3 to 1 respectively as in amounts: manganese 1.65% by weight and silicon 0.45% by weight.
