ABSTRACT:
A metal cored electrode for CO.sub.2 gas shielded welding has 5% to 30% core ingredients in a ferrous metal tube with a seam. The core includes, based upon the weight of the electrode: from about 0.01% to about 0.5% cesium, from about 0.1 to about 3.0 cesium/other alkali metal(s) on a weight basis, the other alkali metals selected from the group consisting of lithium, sodium, potassium and rubidium; and
