Penetration control during welding is an important function of intelligent welding robot. Therefore the visual monitoring and oscillation model of the molten pool were investigated to estimate and control the back bead width in TIG arc welding of thin steel plates. In this study, a welding penetration control system, in which the welding process is monitored via an arc sensor and a visual sensor, is constructed. The effectiveness of the system is demonstrated by automatic welding experiments of thin stainless steel plates.
