Trajectory Control for Robotic Arc Welding Applications
Keyword(s):
Abstract In this study, a PC based program is developed for robotic welding applications. This program includes synthetic generation of Cartesian trajectories based on prespecified points on the trajectory and predetermined velocity profile. Such points can be provided in the teach mode or by using a vision system assisted by a special algorithm. The control algorithm is based on the measurement of joint variable positions and rates resulting in a closed-loop system with a model-based part. These algorithms are applied to an industrial robot performing arc welding weaving applications and typical performance curves are obtained under simulated conditions.
