Abstract
The Gas Metal Arc Welding (GMAW) process is one of the most widely used processes for joining materials in manufacturing industry due to its reliability and low operating cost compared to other joining processes. Many effective and reliable welding processes have been developed since the invention of the electric welding process in the late 19^ century. The GMAW process has been developed over the last 40 years and has been found to be very suitable for automated operations. Many developments have directed place in the automation of the welding process particularly in the area of torch motion and seam tracking and robotic welding. Control of the welding process itself is critically important if full automation of the process and unmanned operation are to be achieved. Although robotic welders have replaced human welders in many welding application, and satisfactory seam tracking systems are available conmiercially, the process control systems have received less attention for a number of reasons such as the complexity of the welding process and lack of advanced control theory. Much of the current research effort is directed techniques to establish an optimal solution for the above problems.
