With the popularization and development of welding robot, robotic intellectualized welding technology will be the main trend of future development. This paper mainly introduces some sensor technology of robotic welding intellectualization in Shanghai Jiao Tong University of China, especially the vision sensor, such as passive vision, active vision and active-passive vision technology, etc. All these studies are just the beginning, and deeper research is still needed.
