Claim Text:
1. A method of forming a flux-cored electrode containing essentially spherical particles of magnesium without a step of crushing said magnesium particles comprising: sizing said essentially spherical magnesium particles by sieving to a range between approximately 0.002 inches to 0.025 inches in diameter, said essentially spherical magnesium particles having been formed by gas atomization of molten magnesium, said essentially spherical magnesium particles comprising more than 99% free metallic magnesium and no more than 0.030% iron oxide and less than 0.002% carbides; adding fluxing particles, metal alloying particles and deoxidizing particles comprising at least said spherical magnesium particles into a trough of a sheath; closing said sheath into a generally cylindrical configuration; sizing said sheath by drawing through a drawing die; and baking said sheath in a heating oven at between approximately 400-700° F. in which said spherical magnesium particles remain elemental magnesium with the natural mass reactivity characteristic of magnesium metal and not a more reactive surface of a crushed particle of magnesium.
