Patent Images
1. A method of tracking a welding operation, said method comprising:
- providing a workpiece;
providing a multiple frequency electromagnetic transmitter;
providing a plurality of welding tools, wherein each welding tool is associated with a tracking sensor that includes an electromagnetic receiver;
determining a set of frequencies for use by the transmitter and the receivers;
providing the determined set of frequencies to the transmitter and the receivers;
transmitting signals from the transmitter to each receiver, wherein the transmitter broadcasts signals at frequencies according to the determined set of frequencies;
receiving signals by each receiver at the determined set of frequencies; and
determining orientation and position of each receiver based on the received signals.
