Metal inert gas welding has wide application in many industries due to its advantages such as high reliability, all position welding capability, low cost, easy operation and high productivity etc. To increase the productivity and decrease the cost advanced techniques must be used in welding. Activating flux is a concept, which used in different welding process like EBW, LBW, and PAW. The flux ingredient, which is inorganic compound (which can be used to produce deep penetration and arc constriction) are available in variety of range and compositions. In the present work, an attempt has been made to use of activated flux for improving depth-to-width ratio as well strength of welding joint. In present years heavier thicker job require so obviously need for reduce angular distortion, higher depth of penetration and as well as number of passes so decrease in cost is direct affect on productivity enhancement. Adding some various types of Shielding gas mixture to get optimum result. The properties of weld metal deposited were evaluated & compared. It was found that the weld metal obtained using activated flux showed very few changes in terms of physical Appearance, Stability, Weld Bead Geometry Mechanical Destructive Testing like Tension Testing of Welding was passed. Brinell Hardness Test was Tested Passed Finally Non Destructive Testing of Radiography results of Welding without any defect. The experimental results showed that activating flux aided MIG increased the weld area, hardness and depth of penetration and also to reduce the angular distortion of the weldment. The flux are used to may MgCO3, Cr2O3, Fe2O3, FS12 ,MnO2 and Cdcl2 further used different kind of combination of fluxes to produced the most noticeable effect. Furthermore, the welded joint to improve better mechanical properties like tensile strength and hardness etc.
