AUTOMATIC WELDING SYSTEM

摘要

An automatic weld programming system is described which is particularly suited for arc welding and in which a plurality of photocells is moved across a program sheet positioned on a console screen. The sheet contains coded indicia which cause signals to be generated to automatically control various welding parameters and synchronize various welding operations to insure that the physical welding manipulations occur in a preselected order and at a programmed rate. In addition, auxiliary system controls are also programmed so that weld environment is precisely controlled before, during and after the welding operation.
