Abstract
In order to achieve the dual}eam laser welding for T-joint,the dual-beam laser welding platform based on multiaxis computer numerical control machine tools and the seam tracking control based on vision sensors were adopted.Theoretical analysis and experiments were carried out,including the welding trajectory planning according to the established mathematic model of welding platform,the design of the position loop based on proportional,integral,derivative control and the algorithm of high speed tracking to improve the accuracy of the tracking system etc.Finally the proposed algorithm was verified in the welding experiments.The results show that the welding tracking control system can eliminate the deviation during laser weldingprocess with a high speed and a high precision by means of dynamic compensation,and can do the dual-beam laser welding for T-joint well.
