Description
Karl Becker in Dortmund-Eving Schweißen unter Wasser mit dem elektrischen LichtbogenKarl Becker in Dortmund-Eving Welding underwater with an electric arc
Patentiert im Deutschen Reiche vom 29. April 3932 ab Patenterteilung bekanntgemacht am 25. Januar 1940Patented in the German Empire on April 29, 3932 Patent issued January 25, 1940
Die Erfindung besteht in der Verwendung von Metallelektroden mit einer Umhüllung, die außen wasserbeständig ist und in der Weise abbrennt oder -bricht, daß sie auf dem Werkstück aufgesetzt bleiben kann, für die elektrische Lichtbogenschweißung unter Wasser. Zweckmäßig besteht die Umhüllung aus einem Gemisch von Wasserglas und Kreide. Bekanntlich bot das Schweißen unter Wasser mit dem elektrischen Lichtbogen bisher fast unüberbrückbare Hindernisse, weil es dem Taucher infolge der Eigenart der Taucharbeit nicht möglich war, den Lichtbogen immer in der für das Schweißen nötigen Entfernung vom Werkstück zu halten.The invention consists in the use of metal electrodes with a sheath, which is water-resistant on the outside and burns or breaks in such a way that it is on the Workpiece can remain in place for electric arc welding under water. The envelope expediently consists of a mixture of water glass and chalk. As is well known, welding offered underwater with the electric arc hitherto almost insurmountable obstacles because of the Diver due to the nature of the diving work was not able to keep the arc in the necessary distance from the workpiece for welding.
Nach der Erfindung gelingt es auf überraschend einfache Weise, das Schweißen unter Wasser sicher zu gestalten. Die Umhüllung bricht beim Niederschmelzen der Metallelektrode laufend so ab, daß sie an der Spitze einen Krater bildet, der den erwünschten Abstand zwischen Schweißstab und Werkstück ergibt. Man kann also eine solche Elektrode in der Weise verwenden, daß sie auf dem Werkstück ständig aufgesetzt bleiben kann, so daß auch bei unbeabsichtigten und unvermeidlichen Bewegungen des Tauchers der Zusammenhang mit dem Werkstück und damit der Lichtbogen gewahrt bleibt.According to the invention, it is possible in a surprisingly simple manner, the welding under Making water safe. The covering breaks when the metal electrode melts down continuously in such a way that it forms a crater at the tip, the desired distance between the welding rod and the workpiece. So you can use such an electrode in such a way that it is on the Workpiece can stay put on, so that even in the case of unintentional and inevitable Movements of the diver, the connection with the workpiece and thus the arc is preserved.
Umhüllte Elektroden für die elektrische Lichtbogenschweißung, die in der Weise abbrennen oder -brechen, daß sie auf dem Werk-», stück aufgesetzt bleiben können, sind zwar! bereits bekannt, es war jedoch neu, daß sie* mit Vorteil für die Lichtbogenschweißung unter Wasser verwendbar sind. Man kann also bestimmte, bereits im Handel befindliche umhüllte Elektroden verwenden. Diese müssen aber in den meisten Fällen zum Zwecke der Verwendung unter Wasser noch mit einem Anstrich von Wasserglas oder einem ähnlichen, die auflösende Wirkung des Wassers auf die Umhüllung verhindernden Anstrich versehen werden.Covered electrodes for electric arc welding, which burn off in this way or break so that they can remain attached to the workpiece, are indeed! already known, but it was new that they * were beneficial for arc welding are usable under water. So you can buy certain ones that are already on the market use covered electrodes. In most cases, however, these must be used for the purpose of Use under water with a coat of water glass or a similar one, the dissolving effect of the water on the coating can be provided.
