Abstract: A manufacturing method is presented for manufacturing cored welding electrode, including provision of a cored electrode structure with core fill material substantially enclosed within a sheath material, and application of a sodium based feeding lubricant to the cored electrode structure. A cored welding electrode is provided, including a tubular sheath material with a center core area, a core fill material within the core area, and a sodium based lubricant coating on the sheath material, wherein the lubricant comprises sodium sulfate, sodium carbonate, and/or sodium nitrite.

Abstract: A method of AC welding that includes the step of supplying AC current with a given waveform from a power source to an advancing electrode and workpiece. The AC current is used to melt the electrode and to thereby deposit metal from the electrode onto the workpiece. The electrode includes a particulate arc stabilizing compound. The particulate arc stabilizing compound includes sodium and titanium dioxide. The particulate arc stabilizing compound constitutes over 20% by weight of the core of the electrode.

Abstract: A cored electrode to form a weld bead with little or no gas tracking. The cored electrode includes a metal sheath and a fill composition. The filling composition includes a slag forming agent and at least one fluorine containing compound.

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.

Abstract: Methods are disclosed for rating a welding electrode and/or for ranking two or more electrodes with respect to gas tracking effects in gas shielded flux cored arc welding processes. The methods involve performing a standardized welding process using an electrode of interest to create a test weld on a workpiece with a linearly varying contact to work distance in the process, measuring a distance from the beginning of the weld to a point at which gas tracking is first observed, and rating an electrode or ranking several electrodes according to the measured distance.
