Abstract
Description
Die Erfindung betrifft ein Verfahren zum Anschweißen von Abzweigstutzen anThe invention relates to a method for welding branch connections at
Pn:re oder zylindrische Behälter nit einer. @nterpulverschweißbrenner, welcher mittels einer auf den Stutzen aufgesetzten Drehvorrichtung parallel zur Stutzenachse entlang der Durchdringungslinie geführt wird.Pn: right or cylindrical container with one. @ nter powder welding torch, which by means of a rotating device placed on the nozzle parallel to the Nozzle axis is guided along the penetration line.
ei diesem bekannten Verfahren wird der Stutzen nach den Anpassen auf das Rohr aufgesetzt, geheftet und zunächst dessen @urzellage von Hand geschweißt. Dann wird der Stutzen senkrechtstehend aufgespannt und die Drehvorrichtung für den Schweißbrenner auf den Stutzen befestigt. Anschließend wird der Schweißvorgang einneleitet. Der Schweißkopf dreht sich dabei un die vertikale Stutzenachse und folgt der Durchdringungslinie, wobei er sich entsprechend letzterer hebt und senkt. Lr beschreibt also Kurven, die aus 1er Dreh- und @ubbewegung resultieren und die über ein Getriebe miteinander gekoppelt sind.With this known method, the nozzle is opened after the adjustment the pipe is put on, tacked and first of all its root layer welded by hand. Then the nozzle is clamped vertically and the rotating device for the Welding torch attached to the nozzle. The welding process is then initiated. The welding head rotates along the vertical nozzle axis and follows the penetration line, whereby it rises and falls according to the latter. Lr describes curves, which result from 1 rotation and @ub motion and which are connected to each other via a gear are coupled.
Der @it diesem bekannten Verfahren bestehende Machteil besteht darin, daß die Durchmesser der einzuschweifenden Abzweigstutzen einen Verhaltniswert von d/D = max. 0,6 nicht überschreiten können (d=Stutzendurchmesser, D= Rohrdurchmesser). Bei größeren Stutzendurchmessern würden nämlich das Schweißbad und die Pulverabdeckung aus den seitlichen Schweißfugen der Durchdringungslinie ablaufen. The disadvantage of this known method is that that the diameter of the branch pipe to be looped has a ratio of d / D = max. 0.6 (d = nozzle diameter, D = pipe diameter). In the case of larger nozzle diameters, the weld pool and the powder cover would be run out of the side welding joints of the penetration line.
Der Frfindung liegt die Aufgabe zugrunde, ein Verfahren zu schaffen, mit welchen die angegebenen nachteile vermieden und Abzweigstutzen angeschweißt werden können, deren Durchmesserverhältnis wesentlich größer ist und die bis zu einem Wert von nahezu d=1 betragen kann.The invention is based on the task of creating a process with which the specified disadvantages are avoided and branch connections are welded on can be whose diameter ratio is much larger and which up to can be a value of almost d = 1.
D !)ie Lösung der rufgabe ergibt sich aus dem Patentanspruch. D!) He solution of the task results from the patent claim.
In den Zeichnungen ist ein Ausführungsbeispiel der Erfindung dargestellt.In the drawings, an embodiment of the invention is shown.
Es zeigen: Fig. 1 die Schweißeinrichtung von der Seite, Fig. 2 eine stirnseitige Ansicht, Fir. 3a - 3c verschiedene Schweißpositionen.They show: FIG. 1 the welding device from the side, FIG. 2 a frontal view, Fir. 3a - 3c different welding positions.
Pas Rohr 1, an welchen der Abzweigstutzen 2 angeschweißt werden soll, ist einseitig in der Drehvorrichtung 3 eingespannt und ruht auf dem Rollenbock 4. Nach dem in bekannter Weise erfolgenden Aufsetzen, Anheften und Festspannen des Stutzens 2 wird die Drehvorrichtung 5 für den Schweißbrenner 6 mit seiner Seitenverstellung 7 und der Hähenverstellung 8 in etenfalls bekannter Meise auf dem Stutzen 2 befestigt. Der Schweißdraht 9 wird dem Schweißbrenner von der Drahttrommel 19 zugeführt.Pas pipe 1, to which the branch connection 2 is to be welded, is clamped on one side in the rotating device 3 and rests on the roller block 4. After putting on, tacking and tightening the in a known manner Connector 2 is the rotating device 5 for the welding torch 6 with its side adjustment 7 and the height adjustment 8 attached to the socket 2 in some known tit. The welding wire 9 is fed from the wire drum 19 to the welding torch.
Gemäß Fig. 3a werden der Stutzen 2 durch Drehen des Rohres 1 zunachst in eine annähernd waagerechte Position und der Schweißbrenser 6 in seine Ausgangsstellung gebracht, worauf der Schweißvorgang beginnt. Wahrend der Schweißbrenner langsam den Stutzen unkreist und dabei der Purchdringungslinie folgt, wird das Rohr mit entsprechender Geschwindigkeit um seine @angsachse @edreht, und zwer in der Weise, daß die momentane Schweißstelle in etwa waalerechter Lage bleibt. In Fiy. 3h ist die Mittelstellung und in Fig. 3c die Endlage dargestellt, welche nach einer Rohrundrekung von etwa 130° erreicht ist.According to FIG. 3 a, the connecting piece 2 is initially made by rotating the tube 1 into an approximately horizontal position and the welding torch 6 into its starting position brought, whereupon the welding process begins. While the welding torch slowly If the nozzle is not circled and follows the purchase line, the pipe is with corresponding speed around its @ axis @ rotated, and in such a way, that the current welding point remains in an approximately horizontal position. In Fiy. 3h is the middle position and in Fig. 3c the end position is shown, which after a pipe unrection of about 130 ° is reached.
Die Abstimmung bzw. Regelung von Drehvorrichtung 3 für das Rohr 1 und der Drehvorrichtung 5 für den Schweißbrenner 6 kann mit üblichen Mitteln erfolgen. vorzugsweise unter Verwendung von @ikroprozessoren.The coordination or regulation of the rotating device 3 for the pipe 1 and the rotating device 5 for the welding torch 6 can be done by conventional means. preferably using microprocessors.
