2D YAG welding on non-linear trajectories with 3D camera seam tracker following for automotive applications

Abstract

This article presents an experimental proposal for non-linear blank YAG welding with an industrial robot. First, we present the system. At the end of the robot, an actuator supports the focusing head and a 3D sensor. This system will allow correcting the trajectory before welding. The system is described. Then, we present the trajectory programming and the modifications made in order to control the focal spot and sensor position and orientation. Finally, we demonstrate the process by welding YAG cut blanks.
