Integrated robotic system development for arc-welding application with artificial vision

Abstract

The authors describe the concept, development, and operation of an arc-welding industrial robot to which have been joined a vision system and a computer for controlling and synchronizing the integration. The vision system makes it possible to determine the exact point where the robot must perform the arc-weldings. A communications protocol makes it possible to communicate between the robot and the computer and to synchronize the operation of the vision system (robot-computer). It is concluded that the arc-welding robot integrated with a vision system allows improved control of the weld process and the total elimination of welding errors caused by deformations on the weld-piece geometry.<>
