The present invention relates to a flux cored electrode used in electric arc welding and more particularly to the use of a specific form of magnesium particles in the core of the electrode or wire.

Flux cored electrode

A titanium based welding flux that includes titanium dioxide and a moisture resistant agent. The titanium oxide includes purified titanium dioxide that includes little or no impurities that can act as nucleation sites for carbide formation in a weld metal. The moisture resistant compound includes a colloidal metal oxide.

Modified flux system

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.

Method of AC welding using a flux cored electrode

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.

Flux cored electrode with fluorine

A welding flux that includes a flux agent, water glass and colloidal compound formed from small particles of silicon dioxide. The welding flux has a very low hygroscopicity, thus is well suited from low hydrogen electrodes.
