Abstract: A system and device for welding training. In one example, a welding training system includes a display configured to show welding features related to a training welding operation. The system also includes a training workpiece having a substantially transparent weld joint configured to be placed adjacent to the display during the training welding operation. The system includes a processing device coupled to the display and configured to provide welding data relating to the training welding operation to the display. The system also includes a training torch comprising an optical sensor. The training torch is coupled to the processing device and configured to provide the processing device with data from the optical sensor corresponding to a position of the training torch relative to the training workpiece.

Abstract: A breakaway buckle has a keeper attachable to a first strap and a secure attachable to a second laterally disposed strap. The secure has a tongue releasably retained in the keeper by overlapping interlocked locking surfaces on both components. Cam surfaces on the secure and keeper coact in response to lateral and/or torsional forces exerted on the secure to reduce the area of overlap between the locking surfaces and thereby facilitate separation of the secure from the keeper.
