GMA Welding is a profoundly used technique in the joining industry. GMA Welding is used in automatic or semiautomatic modes depending upon the requirements. The versatility, portability, and lesser requirements for highly skilled labour
to produce high quality welds makes it a better choice for joining purposes for small jobs as well as mass production. Due to the
vast number of applications of the process, there is a need to construct a relationship between various user controlled parameters
and the weld quality. In governing the mechanical properties of the weld, the weld bead plays a major role. Depending upon the
values of the process parameters such as voltage, wire feed rate (WFR), torch angle, nozzle to plate distance(NPD) and welding
speed, the geometrical properties of the weld bead such as width, penetration and weld reinforcement height are determined. The
present investigatory work aims at developing a mathematical model to determine the weld bead geometry and shape parameters
