Dr. Hartmut Kotowski, 7800 Freiburg gorrichtung für eine blendfreie optische Kontrolle einer Schweißstelle vor und nach Beginn des SchweißVorganges.Dr. Hartmut Kotowski, 7800 Freiburg Device for a glare-free optical inspection of a welding point before and after the start of the welding process.

Die große Helligkeit die beim Schweißen entsteht, muß abge-I dunkelt werden, damit der Schweißer den Schweißvorgang be- ;&iacgr; obachten und steuern kann. Dies geschieht z. B. durch ein lichtabsorbierendes Glas. Diese Lichtabsoption ist ah~r zn stark, um bei normaler Helligkeit durch das liehtabsorbi^rende G-las genügend sehen zu können. Um die Schweißstelle vor dem &igr; Schweißen sehen zu können, muß entweder das lichtabsorbierende Glas hochgeklappt oder hochgeschoben werden. \ Zweck der Erfindung ist,eine Vorrichtung zu schaffen, die \ auf einfache Weiö-e einen Wechsel von offener Sicht auf die \ Schweißstelle zu IichtgesChUt1Ster Sicht und umgekehrt I ermöglicht.
% The great brightness that occurs during welding must be darkened so that the welder can observe and control the welding process. This can be done, for example, using light-absorbing glass. This light absorption is too strong to be able to see sufficiently through the light-absorbing glass in normal brightness. In order to be able to see the welding point before welding , the light-absorbing glass must either be folded up or pushed up. The purpose of the invention is to create a device that enables a simple change from an open view of the welding point to a light-shielded view and vice versa.
%

I Diese Aufgabe wird in der Erfindung auf folgende Weise j · gelöst:
i Das Sichtfeld in dem Schweißschutzhelm ist in 2 Felder unter- &iacgr; teilt. Das obere Feld ist durch lichtabsorbierendes Glas geil I This object is achieved in the invention in the following manner j ·:
i The field of vision in the welding helmet is divided into 2 fields. The upper field is made of light-absorbing glass

1 schützt. (1 in Abb. I ) Dadurch kann der SchweißVorgang beobachtet werden. Im unteren Feld sind Lamellen so angeordnet^ X daß man bei schrägem Blick naoh unten zwischen ihnen hindurch- \ sehen kann ( 2 in Abb. I ). Hebt der Schweißer den Kopf mit h dem Schutzhelm, so kann er durch die Lamellen im unteren f Felde die Schweißstelle sehen und z. B. das Schweißgerät an die richtige Stelle des zu schweißenden Werkstückes bringen. Dann senkt der Schweißer den Kopf mit dem Schutzhelm, bringt das Feld mit dem lichtabsorbierenden Glas vor seine Augen und der Schweißvorgang kann beginnen. Von der Schweißstelle kann jetzt durch die schräggestellten Lamellen kein Licht dringen, zumal wenn die Oberflächen der Lamellen dunkel gefärbt sind. 1 protects. (1 in Fig. I ) This allows the welding process to be observed. In the lower field, slats are arranged in such a way that when looking at an angle you can see through them below ( 2 in Fig. I ). If the welder raises his head with the protective helmet, he can see the welding point through the slats in the lower field and, for example, bring the welding device to the right place on the workpiece to be welded. The welder then lowers his head with the protective helmet, brings the field with the light-absorbing glass in front of his eyes and the welding process can begin. No light can now penetrate from the welding point through the angled slats, especially if the surfaces of the slats are dark.

Ist der SchweißVorgang beendet, so hebt der Schweißer seinen Kopf mit dem Helm wieder und kann durch das PeId mit den Lamellen die Schweißstelle sehen, beurteilen und Schlacke abklopfen. Der Schweißer hat dabei beide Hände frei.Once the welding process is finished, the welder lifts his head with the helmet again and can see the welding point through the slatted panel, assess it and knock off slag. The welder has both hands free.

Schutzansprüche Dr. Hartmut Kotowski, 7800 Freiburg Vorrichtung für eine blendfreie optische Kontrolle einer Schweißstelle vor und nach Beginn des SchweißVorganges.Protection claims Dr. Hartmut Kotowski, 7800 Freiburg Device for a glare-free optical inspection of a welding point before and after the start of the welding process. 1.) Eine Vorrichtung für eine blendfreie optische Kontrolle einer Schweißstelle vor und während des Schweißvorganges, dadurch gekennzeichnet, daß das Sichtfeld im Schutzhelm des Schweißers in zwei Felder unterteilt ist, wobei das obere Feld durch stark lichtabsorbierendes Glas abgedeckt ist ( 1 in Abb. I ) und das untere Feld ( 2 in Abb. I ) zwischen schräggestellten Lamellen den direkten Blick auf die Schweißstelle gestattet. Durch leichtes Heben oder Senken des Kopfes kann der Schweißer also von ungehinderter Sicht auf abgeblendete Sicht umschalten und umgekehrt. 1.) A device for glare-free optical control of a welding point before and during the welding process, characterized in that the field of vision in the welder's protective helmet is divided into two fields, with the upper field being covered by highly light-absorbing glass ( 1 in Fig. I ) and the lower field ( 2 in Fig. I ) between inclined slats allowing a direct view of the welding point. By slightly raising or lowering the head, the welder can switch from unobstructed view to dimmed view and vice versa. 2.) Vorrichtung nach Anspruch 1 dadurch gekennzeichnet, daß die Lamellen aus Metall, Kunststoff oder einer Farbschicht gefertigt sind.2.) Device according to claim 1, characterized in that the slats are made of metal, plastic or a layer of paint. 3.) Vorrichtung nach Anspruch 1 dadurch gekennzeichnet, daß die Lamellen dunkel getönt sind, um nicht zu reflektieren. 3.) Device according to claim 1, characterized in that the slats are darkly tinted so as not to reflect. 4.) Vorrichtung nach Anspruch 1 dadurch gekennzeichnet, daß die Zwischenräume zwischen den Lamellen durch Glas oder durchsichtigen Kunststoff ausgefüllt sind.4.) Device according to claim 1, characterized in that the spaces between the slats are filled with glass or transparent plastic.
