And manual welding, due to the technical level, fatigue, the sense of responsibility, physiological limit and the objective and subjective factors should influence, a long time to keep the welding work stability and consistency. Moreover, due to welding the bad working conditions, are willing to engage in hand welding in decrease, skilled technical workers more shortage trend. On the other hand, electronic technology, computer technology, numerical control and the development of robot technology for welding process automation provides favorable conditions, and has penetrated into all fields of welding. This paper introduces and analyzes the arc welding process typical weld tracking sensor principle, characteristics and application developmen
