Abstract
A cored electrode for arc welding wherein the electrode has a core in which the fill material includes a manganese-containing composite particle. A method for arc welding comprises providing a cored electrode having a core of fill material including a composite particle containing manganese, and applying a voltage to the electrode upon contacting a work piece to cause the electrode to melt and form a weld metal bead.
