INTRODUCTION

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, potassium silicate, sodium silicate and minerals like quartz, calcite and mica. Ferro-alloys are also used in the formulations of fluxes.

The bulk users of welding electrodes are the manufacturers detailed as under: • • • • • Welded Tubes & Pipes Structural fabrication & Construction Ship & Ship ancillaries Industrial machinery tools & equipment; and Misc. users including repairs and maintenance

Welding electrodes are used in different industries viz. • • • • • • Thermal, hydel & nuclear power plants Petrochemical Industry Industrial machinery Heavy engineering Transportation Fertilizers and
