Abstract

Laser welding puts high demands on the robot or manipulator used, as it requires a high tracking accuracy (down to 0.1 mm) at high velocities (up to 250 mm/s). Sensors measuring the position of the laser focal point relative to the seam to be welded are therefore required to make robotic laser welding successful in a production environment. To use sensor information for real-time seam-tracking a special control architecture called trajectory based control has been developed. It uses a trajectory generator based on cubic interpolation, where Cartesian locations (position and orientation) can be added on-the-fly during the robot motion. This way sensor information obtained during the robot motion is used to generate the robot trajectory in real-time.
