Situation and development of interlligentized techonology for arc welding robot

Automatic welding and intelligent welding have been an important means of high productivity and quality welding manufacturing.In this paper,the fundamental research of the intelligent technologies was described comprehensively as follows.It includes visual guide and recognition of the initial weld position,the method of three dimensional seam tracking with vision-arc compound sensor,knowledge modeling and intelligent control strategies and so on.The achievements in these fields expand the research and application area of the robotic arc welding.Integration of the latest research achievements,a climbing obstacle with wheel foot combined all position arc welding robot was developed.At the same time,the system integration of welding robot station was carried out in the field of aerospace,shipbuilding and marine heavy industry.
