1. A method for optimizing a schedule for impulse welding, comprising:

  • generating a weld lobe using a preexisting welding schedule, the schedule prescribing a current, a weld time, and a pressure;

    identifying an operating window on the weld lobe;

    analyzing the operating window, the analysis includingdetermining a maximum time range of the operating window, anddetermining a maximum current range of the operating window;

    until (i) the determined maximum time range of the operating window is greater than a predetermined percentage of the prescribed weld time of the schedule and (ii) the determined maximum current range is greater than the prescribed current of the schedule, creating additional weld lobes by varying the pressure and repeating the identifying an operating window and the analyzing the operating window steps; and

    selecting, within the operating window satisfying conditions (i) and (ii), a second schedule including a second weld time, a second current, and a second pressure.
