In welding of aluminum pipes without control, the heat flow causes too much heating and over penetration at the last quarter, and wide bead or melt down often occurs. In order to avoid these problems and to obtain a uniform weld bead over the entire circumference of the pipe, a new system was developed for automatic Tungsten Inert Gas (TIG) welding of horizontally fixed pipes. In the welding control system, a vision sensor for monitoring the molten pool, welding speed controller and neural networking were adopted. The vision sensor consists of a CCD camera and a specially designed mirror which is set in the pipe, and captures the inner image of the molten pool during welding process. Then, the optimum welding speed which depends on the width of molten pool was calculated by the neural network. Finally, the effectiveness of the welding control system is confirmed by welding control experiments.
