%X The rough set theory, which is proposed by Pawlak, provides a tool for describing uncertainty. This paper discusses the method of building fuzzy model based on the rough set theory, presents concepts of adjustment and expansion, and the dynamic model of pulse TIG welding process is built by the proposed method. The validations of models are done and the results show that the method is effective.
