Description

Um gute Schweißverbindungen herzustellen, hat man schon vorgeschlagen, das Verbindungsmetall und die Schweißflächen durch eine Schweißflamme in teigartig bildsamen Zustand zu bringen und beide in diesem Zustand mittels Schlagwerkzeuge zu vereinigen. Bei einer solchen Arbeitsweise muß der Schweißer zunächst in der einen Hand den Schweißbrenner und in der anderen den Schweißstab führen. Will er dann das jeweils geschweißte Stück der Schweißnaht hämmern, so muß er den Schweißstab weglegen und den Brenner gegen den Hammer vertauschen.In order to produce good welded connections, it has already been proposed to use the connecting metal and to bring the welding surfaces into a dough-like formable state by means of a welding flame and both in this state to unite by means of striking tools. In such a way of working, the welder must first hold the one hand The welding torch and the welding rod in the other. Is that what he wants in each case hammer the welded piece of the weld, so he must put the welding rod away and the Swap the burner for the hammer.

Gegenstand der Erfindung ist nun einThe invention is now a

>5 Schweißverfahren, bei dem die zu verschweißenden Werkstoffenden zunächst auf Schweiß-"wärme gebracht, der Schweißzusatzwerkstoff alsdann lagenweise in die Naht eingetragen und jede Lage, nachdem sie teigig und bildsam geworden ist, durch Hämmern verdichtet wird. Erfindungsgemäß wird die Verdichtung· dabei durch von der Mündung des Schweißbrenners ausgehende, sich taktmäßig wiederholende Druckstöße bewirkt, die durch ruckweises An- > und Abstellen der Brenngasoder Sauerstoffzufuhr zum Brenner oder auf sonstige Weise an der Mündung des Schneidbrenners herbeigeführte Explosionen, also durch absichtliches Knallenlassen des Brenners, entstehen.> 5 welding processes in which the The ends of the material are first brought to the welding heat, and the filler metal is then introduced into the seam in layers and each layer, after it has become doughy and malleable, compacted by hammering will. According to the invention, the compression is carried out by the mouth of the Welding torch's outgoing, cycle-wise repeating pressure surges caused by Jerky switching on and off of the fuel gas or oxygen supply to the burner or on other way caused explosions at the mouth of the cutting torch, ie caused by deliberately popping the burner.

Gegenüber dem Verdichten mit dem Handhammer wird dadurch der Vorteil erzielt, daß das Aufschmelzen und Verdichten des Werkstoffes mit ein und demselben Gerät vorgenommen werden kann.Compared to compacting with a hand hammer, this has the advantage that the melting and compression of the material is carried out with one and the same device can be.

Um Verunreinigungen und Schlacken aus dem Schmelzbad fernzuhalten, wird die Schweißstelle gemäß der Erfindung vor dem Eintragen des Schweißzusatzwerkstoffies dadurch gereinigt, daß man sie denselben sich taktmäßig wiederholenden Druckstößen aussetzt und auf diese Weise den feinen Staub und die fest anhaftenden Schlackenteilchen o. dgl. wegbläst.To keep impurities and slag out of the weld pool, the Welding point according to the invention before entering the welding filler material thereby cleaned so that they are exposed to the same pressure surges which are repeated in rhythm and in this way blows away the fine dust and the firmly adhering slag particles or the like.

Das Hervorrufen der die Verdichtung bewirkenden Explosionen an der Brennermündung bereitet bei entsprechend eingerichteten Brennern kerne Schwierigkeiten. Durch taktmäßigen Anschlag von in die Gas- oder Sauerstoffzuleitungsrohre des Brenners eingebaute Ventile läßt sich das Gas-Luft-Gemisch während des Schweißens so schnell und ruckartig verstellen, daß die gewünschten Explosionen an der Mündung des Schweißbrenners entstehen.Causing the compression causing explosions at the burner mouth causes no problems with appropriately set up burners. By Timed stop of built into the gas or oxygen supply pipes of the burner Valves, the gas-air mixture can be adjusted so quickly and jerkily during welding that the desired Explosions occur at the mouth of the welding torch.
