Description
Beim autogenen Schweißen unter Gasschutz ist es bekannt, als Schutzgas Stickstoff oder Kohlensäure zu verwenden, um dadurch schlackenloses Schweißen zu erzielen. Die Verwendung dieser Schutzgase bedingt, daß man, um gute Resultate zu erzielen, das Schweißen unter einer Schutzhaube vornimmt, was die Ausführung kompliziert.In the case of gas-shielded gas welding, it is known as shielding gas To use nitrogen or carbon dioxide in order to achieve slag-free welding achieve. The use of these protective gases requires that you get good results achieve, the welding makes under a protective hood, which complicates the execution.
Beim Verfahren nach vorliegender Erfindung verwendet man als Schutzgas Wasserstoff, wobei man eine Schutzhaube nicht benötigt.In the method according to the present invention, the protective gas is used Hydrogen, whereby a protective hood is not required.
Als Vorrichtung zur Ausführung des Verfahrens bei autogenen Außenschweißungen dient ein Schweißbrenner mit einer zentralen Öffnung für den Austritt des Schweißgasgemisches und mit einem die zentrale Öffnung umgebenden Kranz von Öffnungen für den Austritt von Wasserstoff. Der bei der Anwendung dieses Brenners die Schweißflamme einhüllende Mantel der ringförmigen Wasserstoffflamme verhindert den Zutritt von Luftsauerstoff zur Schweißstelle und ermöglicht so ein schlackenloses Schweißen.As a device for carrying out the process with oxy-fuel external welds a welding torch with a central opening is used for the discharge of the welding gas mixture and with a ring of openings for the exit surrounding the central opening of hydrogen. The one that envelops the welding flame when using this torch The jacket of the ring-shaped hydrogen flame prevents the entry of atmospheric oxygen to the welding point and thus enables slag-free welding.
Um Schweißungen im Innern eines Rohres schlackenlos vorzunehmen, wird zweckmäßig der Wasserstoff durch das Rohr geleitet und an der Austrittsstelle aus demselben entzündet, um die Bildung von Knallgas zu vermeiden.In order to make welds inside a pipe without slag, expediently the hydrogen passed through the tube and out at the outlet ignited the same in order to avoid the formation of oxyhydrogen.
Ein Ausführungsbeispiel einer Vorrichtung gemäß der Erfindung ist in der Zeichnung in Fig. i im Axialschnitt und in Fig. 2 im Grundriß dargestellt. Mit i ist das Gehäuse des Schweißbrenners @ezeichnet, welches eine zentrale Öffnung 2 aufweist; durch welche das die Schweißflamme bildende Gasgemisch, das bei 3 zugeführt wird, austritt. Auf das Brennergehäuse ist ein Mantel q. aufgesetzt, welcher einen Raum 5 einschließt, dem durch Leitung 6 Wasserstoff zugeführt wird, der aus einem die zentrale Öffnung 2 umgebenden Kranz von öffnungen y austritt. Der so gebildete Mantel der ringf"igen Wasserstoffflamme verhindert den Zutritt von Luftsauerstoff zur Schweißstelle.An embodiment of a device according to the invention is shown in the drawing in Fig. i in axial section and in Fig. 2 in plan. The housing of the welding torch @ is marked with i, which has a central opening 2 has; through which the gas mixture forming the welding flame is supplied at 3 will emerge. A jacket q is placed on the burner housing. put on, which one Includes space 5 to which hydrogen is fed through line 6, from a the central opening 2 surrounding ring of openings y exits. The so educated The jacket of the ring-shaped hydrogen flame prevents the entry of atmospheric oxygen to the welding point.
