Systems and methods providing contact tip to work distance (CTWD) feedback for augmented reality

摘要

A system and method to make a welder aware of contact tip-to-work distance (CTWD) during a welding process. One or both of welding output current and wire feed speed is sampled in real time during the welding process. The actual CTWD is determined in real time based on at least one or both of the sampled welding output current and wire feed speed. The actual CTWD may be compared to a target CTWD in real time, where the target CTWD represents an estimated or desired CTWD for the welding process. A deviation parameter may be generated based on the comparing. An indication of the deviation parameter or the actual CTWD may be provided to a welder performing the welding process as feedback, allowing the welder to adjust the actual CTWD to better match the target CTWD in real time during the welding process.
