Abstract

Abstract A structure for a CAD based, task level off-line programming system for robotic arc welding is presented. The welding task is specified using a solid modeling CAD system. A model of the robot motion capabilitie are used to plan the path of motion between weld seams for the robotic welding process. The output of the system, in the form of a robot level program, is transferred to a specific robot controller using an interface module, which was also created for this research. An example welded part is used to show that the system can enhance the productivity and efficiency of robotic arc welding, for both low batch and high batch production.
