1. A real time control system for controlling predetermined operating characteristics of a welding mechanism movable along a workpiece joint to be welded, said workpiece joint having two opposed edges, said system comprising:

  • thermal radiation sensing means responsive to thermal radiation energy emanating from a heated workpiece joint, said sensing means being positioned along a travelling path of a welding element of said welding mechanism, ahead of and in close proximity to said welding element, said sensing means and welding element being disposed on a common side relative to said workpiece joint;

    means for causing said thermal radiation sensing means to scan said workpiece joint along a line transverse to said travelling path so as to allow said sensing means to sense a thermal radiation profile along said transverse scanning line and to provide peak signals representative of the relative position of the edges of said workpiece joint in accordance with the thermal radiation profile sensed, thereby defining the actual width of said joint; and

    circuitry means for processing said peak signals provided by said radiation sensing means to issue command signals for controlling said predetermined operating characteristics of said welding mechanism.
