One of the important problem in welding engineering is to develop a mathematical method for the determination of optimal process parameters.<BR>From this viewpoint, an algorithm for the determination of optimal heat input condition of arc welding has been discussed in the previous paper, where an analytical model of heat conduction has been used to evaluate the temperatuer field during welding and the nonlinear programming technique has been applied to estimate the optimal heat input sequence for a required temperature field.<BR>In this paper, the optimal heat input sequence derived from the above method has been discussed experimentally and as a result of the comparison between experimental and required temperature fields, it is made clear that the algorithm for optimal heat input sequence is reliable.<BR>In the second part of this paper, a computerized optimal control system for thin plate GTAW has been developed on the basis of the algorithm, where the arc efficiency is continuously identified by the temperature detected by IR sensor. Under the system, a real-time and adaptive optimization of process parameters is possible by taking account of the actual arc efficiency.<BR>From the satisfactory result of experiment on the system, it is concluded that the algorithm described in the previous paper is a useful guide for optimal heat input control of arc welding.
