ABSTRACT:
A manufacturing process is disclosed for manufacturing cored welding electrode, wherein calcium based drawing lubricant is applied to an outer surface of a flux cored welding electrode structure, and a drawing process is thereafter carried out to compact the core fill material and to set the final outer wire diameter. Cored welding electrodes are disclosed having calcium hydroxide within the electrode core, on the sheath, and/or in a sheath seam.
