Abstract

Gas Metal Arc Welding (GMAW) has got many wide applications in today's industry. Selection of input welding parameters in this process plays a very major role depending on which the quality of weld and subsequently the productivity depends. Controlling of the input parameters is very much essential to obtain a good quality weld. In the present work some of the parameters such as, welding voltage, welding current, welding speed, Nozzle to Plate Distance (NPD) and Gas Density (G) influencing weld deposit area in Gas Metal Arc welding process are studied by carrying out experimentations and also a mathematical model has been developed for achieving better weld deposit area in a mild steel specimen. Factorial design approach is applied for finding the relationship between the various process parameters and weld deposit area. The study discovered that, the welding voltage and Nozzle to Plate Distance is varying directly with weld deposit area and a direct relationship existing between the welding current and speed with weld deposit area is observed.
