Written by a pioneer in the field, Arc Welding Control covers all aspects of this emerging technology. Part 1 quantitatively describes the dynamic behaviour of arc welding, the power sources used, and their effect on welding technology through the basis of control theory. Part 2 describes new ways of controlling the welding arc through modern electronics. Part 3 establishes the first mathematical model of the arc sensor on the basis of control theory and Part 4 describes a new method for measuring weldment temperature fields using the colorimetric-imaging method. Finally, Part 5 describes the idea of recognizing weld grooves with a three-dimensional vision system and automatic programming of the weld path.
