Abstract

The characteristics of the image in the optical joint configuration sensing method reported in the previous paper are obtained in connection with the welding condition, such as arc voltage and arc current.
The one or two dimensional parallel processing method, in which the obtained image is converted into binary data by the array of light comparators installed on the screen of the image receiver and the required values are extracted by the logic circuit, is described, in the next stage.
The result of the feedfoward arc welding control with this sensing method is shown as demonstrating the usefulness of the method in the last stage.
All the experiments were performed by CO2 arc welding on the square grooved joint.
