Abstract
A system for and method of tracking elements of a welding system using electromagnetic sensors and an electromagnetic transmitter, the electromagnetic sensors and an electromagnetic transmitter operating at a frequency group that is selected to reduce or avoid interference from other welding systems, such selection being performed manually by a user or automatically as the result of detection of interference at the sensors.
Claims12
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.
