Gas Metal Arc Welding is a process in which the source of heat is an arc format betweenconsumable metal electrode and the work piece with an externally supplied gaseous shield of gaseither inert such as argon, helium. This experimental study aims at optimizing various Gas MetalArc welding parameters including welding voltage, welding current, welding speed and nozzle toplate distance NPD by developing a mathematical model for sound weld deposit area of a mildsteel specimen. Factorial design approach has been applied for finding the relationship betweenthe various process parameters and weld deposit area. The study revealed that the weldingvoltage and NPD varies directly with weld deposit area and inverse relationship is foundbetween welding current and speed with weld deposit area.
