摘要

In this paper, a new method of joint control of seam tracking and welding quality was used. Arc sensor gets the welding deviation information and ultrasonic sensor gets the welding penetration information. Using the fusion algorithm of combination of optimal weight and recursive least square algorithm can improve the accuracy of seam tracking effectively. Putting the fused information and welding penetration information into fuzzy controller with three-input and two-output to realize inspecting the welding quality and improving accuracy of seam tracking at the same time.
