1. A system for optimizing a weld schedule comprising:

  • N welding apparatuses configured to perform welding operations, where N is an integer greater than 1;

    a weld schedule optimization module that is configured to;

    i) receive the weld schedule from a weld schedule source, the weld schedule defining N different weld sequences, each weld sequence defining one or more weld events to be performed by a corresponding welding apparatus of the N welding apparatuses, each one of the weld events defining a weld operation and a duration of the weld operation,ii) for each one of the weld events, determine an amount of electrical current required to perform the weld operation defined by the one weld event;

    iii) determine, at a time point in the weld schedule, a total amount of electrical current required by the N welding apparatuses based on the amounts of electrical current required by the weld events that are scheduled to be performed at the time point, andiv) compare the total amount of electrical current to a maximum current threshold, andv) when the total amount of electrical current exceeds the maximum current threshold, generate a modified weld schedule by modifying one or more of the weld sequences such that at least one of the weld events defined in the one weld sequence is scheduled for a later time point in the weld schedule; and

    a weld control module that is configured to receive the modified weld schedule and controls the N welding apparatuses according to the modified weld schedule.
