Abstract

A welding helmet is capable of providing an image representative of information from an associated welding operation where the image appears in the same focal range as the welding work area.

First claim

What is claimed is:

1. A welding helmet comprising:
a main body portion;
a visual display portion connected to the main body portion, the visual display portion defining a viewing area; and
an information generating mechanism which generates an image on the visual display portion, said image being viewable during a welding operation, wherein a focus of the image is at a focus range associated to a work area of the welding operation.

2. The welding helmet of claim 1 , wherein information displayed in the image includes at least one of a welding current, welding voltage, welding control parameter, welding equipment, statistical information, control settings, capacity representations, alerts, and a representation of a weld.

3. The welding helmet of claim 1 further comprising a camera adapted to view and record a welding operation in the work area, the camera being used to record a welding operation in the work area.

4. The welding helmet of claim 1 , wherein the image includes an image of the welding operation.

5. The welding helmet of claim 1 , wherein the visual display portion allows the welding operation to be viewed at least through at least a portion of the visual display portion.

6. The welding helmet of claim 1 , wherein the information generating mechanism is a projector.

7. The welding helmet of claim 1 , wherein the visual display portion includes at least one reflective surface.

8. The welding helmet of claim 1 , wherein the visual display includes at least one mirror.

9. The welding helmet of claim 1 , wherein the image generating mechanism includes at least one of a screen, a film, and a sheet integrated into the visual display portion.

10. The welding helmet of claim 9 , wherein the film includes at least one of a semi-transparent LCD film and an electro-optic film.

11. The welding helmet of claim 1 , wherein the information generating mechanism includes a stereo projection, including separate images adapted to create a perception of depth.

12. A welding helmet comprising:
a main body portion;
a visual display portion connected to the main body portion, the visual display portion defining a viewing area;
an information generating mechanism which generates an image on the visual display portion, said image being viewable during a welding operation, wherein a focus of the image is at a focus range associated to a work area of the welding operation; and
a camera adapted to view the work area, wherein the camera is connected to the visual display portion to calibrate a depth of the image relative to the work area.

13. A welding helmet comprising:
a main body portion;
a visual display portion connected to the main body portion, the visual display portion defining a viewing area;
an information generating mechanism which generates an image on the visual display portion, said image being viewable during a welding operation, wherein a focus of the image is at a focus range associated to a work area of the welding operation; and
a sensor located outside of said main body portion and in communication with said visual display portion to calibrate a depth of the image.
