Abstract

Abstract: Vision sensing and computer-based image processing technology is used to measure the bead width from the front side, and a set of fuzzy control system for bead width in pulsed TIG welding is developed. According to the arc light features of pulsed TIG welding and its effects on vision measurements, a special method of image capturing and controlling is put forward. Experiment results show that the system is of good control and adaption abilities.

Key words: Bead width, Fuzzy control, Pulsed welding, Vision
