1. A control system for a production line having a production line drive and a resistance welding station, the welding station having a weld gun with a displaceable welding electrode and a displacement sensor coupled to the electrode for generating a displacement sensor signal responsive to displacement of the electrode during welding, the production line being adapted to index a plurality of parts to the resistance welding station for welding the parts together, the control system comprising:

  • a part containment box for receiving improperly welded parts;

    an input sensor disposed within the part containment box for generating an input sensor signal responsive to detection of an improperly welded part; and

    a test computer in communication with the displacement sensor, the input sensor, and the production line drive, the test computer being operative to compare the displacement sensor signal to a predetermined desired displacement signal to identify the improperly welded part and to provide a fault signal for disabling indexing of the production line until the input sensor signal is received indicating that the improperly welded part has been deposited into the part containment box.
