Abstract

The invention relates to a device for metal welding, comprising a shielding element (1) which allows visual monitoring of the working process but protects the eyes from light radiation. The device comprises a video camera (5) which is directable towards the welding zone for recording the welding process in the form of video signals transmitted, via an image processing unit, to a video display unit (7), which the user is able to view and which is placed in or on the inside of the shielding element (1). The image processing unit reads process data from the video signals and presents the same via the video display unit.

Claims

1. A device for metal welding, comprising a shielding element (1) which allows visual monitoring of the working process but protects the eyes from light radiation, characterised in that it comprises a video camera (5) which is directable towards the place of working for recording the working process in the form of video signals transmitted, via an image processing unit, to a video display unit (7), which the user is able to view and which is placed in or on the inside of the shielding element (1), the image processing unit reading process data from the video signal and presenting the same via the video display unit.

2. A device as claimed in claim 1, characterised in that process data from the image processing unit as well as an image of the welding zone are viewable via the video display unit (7).

3. A device as claimed in claim 1, characterised in that the video display unit is combined with a filter glass (9) in such manner that the welding zone is viewable via the filter glass at the same time as process data is presented to the user via the video display unit (10).

4. A device as claimed in claim 3, characterised in that the video display unit (10) is transparent and placed before the filter glass (9).

5. A device as claimed in any one of the preceding claims, characterised in that the video camera (5) is in communication with a video recording unit.
