【Abstract】 An intelligent system for weld seam tracking is proposed. A king of direct taking arc visual sensor is used to detect the weld and a self tuning fuzzy controller is used to minimize the error of the seam tracking.The process of seam tracking can be observed through a monitor,and the parameter setting is realized by man machine dialogue.A new method of seam image processing for determining the weld position on line is also presented.The welding experiments show that the proposed system can realize the accurate seam tracking during the GTAW process.更多还原
