Abstract: The paper introduces the basic principle, structure and distinguishing tactics of the weld seam defects distinguishing expert system based on neural network. According to the characters of weld seam defects, it distinguishes from different levels. Using the parallel processing and oneself learning of neural network, it overcomes some insufficiency of traditional distinguishing methods.
