Mild Steel 1018has been widely used for machining applications like machine rod, parts, studs and bolts etc.shows that good weld ability and also used for carburized parts. Present research paper study the effect of different process parameters such as voltage, welding current welding speed,gas flow rate and gas pressure on mechanical properties like tensile strength and percentage of elongation of MIG welded joints of MS 1018 plates.MIGwelding is a high deposition rate welding process in which wire is continuous feed from a gun. MIG welding offers several advantages like all position capable, long weld can be made, no slag etc. Optimization was done to find optimum welding conditions to maximize tensile strength and percentage elongation of welded joints. The confirmation test was also conducted to validate the optimum parameters settings. From the papers study, it is found that when the welding current, voltage, GFR increased, the tensile strength decreases, but when welding speed increases, the tensile strength also increases.
