Abstract: Described herein are examples of weld tracking systems implemented via a welding helmet. The welding helmet includes weld tracking sensors configured to allow the welding helmet to track a welding-type tool and/or an arc generated by the welding-type tool. The welding helmet also includes helmet tracking sensors configured to allow the welding helmet to track its own position and/or orientation relative to a reference point in the welding environment. By tracking itself as well as the welding-type tool and/or arc, the welding helmet can differentiate between its own movement, and movement of the welding-type tool and/or arc. By knowing the spatial relationship between the different sensors of the welding helmet, the tracking information can be combined and used for weld tracking. By implementing the weld tracking system in the welding helmet, the weld tracking system becomes portable and usable outside of the usual fixed confines of weld tracking systems.
