Path Planning for Robotic Welding of V-bevels on Thick Plate

Abstract Based on the contour-type weld filling strategy, a welding path planning model for thick plate V-bevel robot is established. The model includes parameters such as welding gun position, inclination angle, swing, welding current, etc. It realizes that only 2 different cross-sectional area weld paths are needed for each layer to complete the filling of the bevel, and avoids frequent changes of the welding process parameters. The establishment of this model provides a theoretical basis for the process design of thick plate beveling.
