Welding electrodes are used in welding various metals in the fabrication of equipment for chemical & Allied industries, construction of steel structures such as bridges, factory sheds, in the manufacture of ships, Vehicles and engineering equipment. Mild steel is welded by electrodes to a maximum among all the metals & Alloys. Therefore M.S. Welding Electrode is the most widely used core wire. Besides this, special grade electrodes are being developed for specific applications. Welding electrodes comprise basically of steel core wire and coating ingredients or flux mild steel core wires are used in majority of unalloyed steel electrodes. Besides mild steel, nickel, Nickel-copper, Nickel irons are also used in MIG & TIG welding. Stainless steel wires are also used for welding in fertilizer, chemical & surgical instrument making industry. Coating ingredients are basically rutile, ilmenite, potassium silicate, sodium silicate and minerals like quartz, calcite, wollastonite and mica. Ferro alloys including ferro manganese powders (high carbon, low carbon, extra low carbon), ferro chrome (extra high carbon, high carbon, low carbon and extra low carbon), ferro silicon (atomized and stabilized), ferro titanium, ferro silico manganese are also used as welding fluxes and electrodes raw materials.
