Abstract—Coated electrodes for welding have exhibited their advantages for longer than one century. Many types of electrodes are available for welding. All types of electrodes have their own significance. The present study was carried out to find out the influence of varying concentration of aluminite in the flux composition of various characteristics of metal cored coated electrode for the purpose of developing better and efficient electrode to improve the welding quality. The total information was about increasing the content of aluminite but the whole proportion was to be fixed has been studied in this paper. We have prepared the three types of electrode with various composition of flux including other materials like cellulose, mica, rutile, iron powder, ferromanganse, low carbon, ferromangense, china clay, calcite. Electrodes varying composition was named as 16% aluminite, 47% aluminite and 65% aluminite according to the composition of aluminite. And with these electrodes welding done on mild steel and after that various properties has been studied like tensile testing ,micro hardness, micro structure, weld bead geometry, smoke testing, chemical composition.
