MS-1018 is non-hardened ductile steel belonging to low carbon steel groups. It has been extensively used for machining applications such as machine parts, rods, bolts, studs, etc. It indicates that welding capability is strong and that it is often used for carburized parts. The present study paper studies the effect of various process parameters such as welding current, voltage, gas flow rate, welding speed and gas pressure on mechanical properties such as tensile strength and percentage of elongation of GMAW welded MS 1018 plate joints. GMAW welding is a high deposition rate welding process in which the wire is continually fed by a pistol or a spool. GMAW welding gives a few advantages like all capable places, long welding etc.Optimization was made to find optimal welding conditions to optimize tensile strength and percentage elongation of welded joints. The confirmation test was also performed to verify the desired configurations of the parameters. From the review papers report, it was observed that when welding current, voltage, GFR increased, the tensile strength decreased, but when welding speed increased but also increases the tensile strength.
