基于Kalman滤波的磁控旋转电弧焊缝跟踪偏差预测研究

o solve the problem that less useful information is obtained by using magnetron oscillating arc to scan weld seam, The paper have designed magnetron rotating arc sensor, proposed deviation prediction of Kalman Filter to seam trackingbased on magnetron rotating arc sensor and described the basic principle of the magnetron rotating arc sensor. Position sensor is used to locate the arc. The quarters of the circumferential sampling method, Kalman filter processing,analysis on the basic principles and calculation steps of this method is carried out. So the the weld deviation information of the space curve is obtained. The weighted prediction correction factor is introducted to achieve prediction and correction for the deviation information of the seam. The welding results show that: the method is feasible for automatic seam tracking based on magnetron rotating arc sensor, improve its accuracy and provide a scientific basis for the prediction of the theory and methods used for weld deviation algorithm.
