In this paper, an automatic torch pose planning system for all position welding has been developed, for the purpose of improving flexibility and automatic planning ability of arc welding robot. With the help of relative software, such as camera calibrating, calculation testing and welding torch pose planing, the space information of welding seam was detected firstly through the modules, including computer vision, signal collecting, image processing. Then the welding torch pose optimization database was inquired. Finally the module of off-line programming was carried out. Consequently, the automatic planning of torch pose for arc welding robot was realized. Satisfied experimental results were acquired in all position welding using the established system.
