Abstract: A theoretical analysis of the visional detecting weld pool information and image-getting mechanisms were presented. Four kinds of composite narrow-band filters based on three kinds of mechanism were adopted in consideration of short-circuiting transfer and spray transfer. After studying the ways for sensing the visional signals of the weld pool, the best filter window was obtained. From the window images with distinct weld pool area were acquired. In addition, image-getting mechanisms for passive light source to detect visional information of weld pool were explored, and then the characters of weld pool of MAG were analyzed.
Key words: MAG welding; weld pool information; vision detection; vision acquisition
