Knowledge based information processing of the weld pool using neural network in the robotic welding

摘要

The paper deals with some problems concerning the controlling of the weld pool. The model of the weld pool is represented by using the neural network, since it may be not difficult to describe the model based on state equations. A new method based on the expert's knowledge is proposed to construct the neural network. The learning time of the proposed network is shorter than the conventional neural network. Moreover, the neural network controller (NNC) is proposed for controlling the weld pool.
