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.

First claim

The invention claimed is:

1. A system comprising:
a display configured to show welding features related to a training welding operation;
a training workpiece comprising a substantially transparent weld joint configured to be placed adjacent to the display during the training welding operation such that a portion of the display is visible by looking through the substantially transparent weld joint; and
a processing device coupled to the display and configured to provide welding data relating to the training welding operation to the display.

2. The system of claim 1 , wherein the display is configured to show a virtual weld bead of the training welding operation behind the substantially transparent weld joint of the training workpiece.

3. The system of claim 1 , wherein the display is configured to show a travel speed or a torch angle of a training torch during the training welding operation.

4. The system of claim 1 , comprising a stand configured to support the training workpiece.

5. The system of claim 1 , wherein the substantially transparent weld joint comprises a pattern configured to be detected by an optical sensor of a training torch.

6. The system of claim 5 , wherein the optical sensor comprises a camera configured to receive image data corresponding to the training workpiece.

7. The system of claim 6 , wherein the camera comprises an adjustable lens to change a focal point of the camera.

8. The system of claim 6 , wherein the camera is configured to alter a camera focus based on a distance between the camera and the training workpiece.

9. The system of claim 5 , wherein the optical sensor is configured to detect image data shown on the display.

10. A system comprising:
a display configured to show welding features related to a training welding operation; and
a training workpiece comprising a substantially transparent weld joint configured to be placed adjacent to the display during the training welding operation such that a portion of the display is visible by looking through the substantially transparent weld joint.

11. The system of claim 10 , wherein the display is configured to show an orientation of a training torch during the training welding operation.

12. The system of claim 10 , wherein the display is configured to show a travel speed or a torch angle of a training torch during the training welding operation.

13. The system of claim 10 , wherein the display is configured to show a virtual weld bead formed during the training welding operation behind the substantially transparent weld joint of the training workpiece.

14. The system of claim 10 , comprising a stand configured to support the training workpiece.

15. The system of claim 10 , wherein the substantially transparent weld joint comprises a pattern configured to be detected by an optical sensor of a training torch.

16. The system of claim 15 , wherein the optical sensor comprises a camera configured to receive image data corresponding to the training workpiece, wherein the camera comprises an adjustable lens to change a focal point of the camera.

17. The system of 15 , wherein the optical sensor comprises a camera configured to receive image data corresponding to the training workpiece, wherein the camera is configured to alter a camera focus based on a distance between the camera and the training workpiece.

18. The system of claim 15 , wherein the optical sensor is configured to detect image data shown on the display.

19. The system of claim 10 , comprising a processing device coupled to the display and configured to provide welding data relating to the training welding operation to the display.

20. A system comprising:
a display configured to show welding features related to a training welding operation; and a training workpiece comprising a substantially transparent weld joint configured to be placed adjacent to the display during the training welding operation such that a portion of the display is visible by looking through the substantially transparent weld joint, wherein the substantially transparent weld joint comprises a pattern configured to be detected by an optical sensor of a training torch, and the optical sensor comprises a camera configured to receive image data corresponding to the training workpiece.
