Description

Das Verbinden von Rohren durch elektrische Schweißung wird seit einer Reihe von Jahren mit gutem Erfolg angewandt, wenn die Wandstärke der Rohre nicht zu schwach ist, wenn das Material der Rohre nicht zu hart ist und wenn der geschweißte Querschnitt im wesentlichen nur auf Zug beansprucht ist.The joining of pipes by electrical welding has been used for a number of years Years of successful use if the wall thickness of the pipes is not too weak is when the material of the pipes is not too hard and when the welded cross-section is essentially only stressed on train.

Viel schwieriger wird die Aufgabe, wenn ίο diese Voraussetzungen nur teilweise oder überhaupt nicht erfüllt sind und insbesondere, wenn die Wandstärke gering ist und außer-'diem BiegtrngSjheSuispruchungein in, die Schweißistelle nkieinkommen.The task becomes much more difficult if ίο these prerequisites only partially or are not fulfilled at all and especially if the wall thickness is small and besides -'diem BiegtrngSjheSuissprungein in, the welding point nkieincome.

Dann genügt die Stumpfschweißung des dünnen Rohrquerschnittes nicht, und man ist gezwungen, die Schweißstelle zu verstärken.Then the butt welding of the thin pipe cross-section is not enough and you are forced to reinforce the weld.

Zu dem Zweck hat man die RohrendenThe pipe ends are used for this purpose

selbst vorher nach bekannten Regeln verstärkt und die so verstärkten Endenstümpfe zusammengeschweißt und dadurch einen stärkeren Querschnitt an der Verbindungsstelle erhalten. Weiter hat man passende Rohrstücke in die zu verbindenden Rohrenden hineingeschoben und durch Punktschweißung an einigen Stellen mit ihnen verbunden. Der Erfolg war im wesentlichen der gleiche wie zuvor.even previously reinforced according to known rules and the end stumps reinforced in this way welded together and thus a stronger cross-section at the connection point obtain. Next you have pushed suitable pipe pieces into the pipe ends to be connected and spot welded connected to them in some places. The success was essentially the same as that before.

Eine wesentlich bessere Verbindung wird erfindungsgemäß dadurch erreicht, daß an der Verbindungsstelle Riohxstücke eingesetzt werden, die nach der Schweißstelle hin im Durchmesser verkleinert sind, so daß dort zwischen ihnen und den äußeren Rohren ringartige Zwischenräume entstehen. Bei der Herstellung der Schweißstellen bilden sich dann sowohl an den äußeren Rohren wie an den inneren Einsätzen Schweißwülste; diese wachsen zusammen, so daß ein Schweißquerschnitt entsteht, der ein Vielfaches des Querschnittes der Außenrohre ist.A much better connection is achieved according to the invention that on the Connection point Riohx pieces are used, which are reduced in diameter towards the welding point, so that there between ring-like spaces arise between them and the outer tubes. In the preparation of the welds then form weld beads on both the outer tubes and the inner inserts; these grow together, so that a weld cross-section is created that is a multiple of the cross-section the outer tube is.

Das Verfahren wird durch das auf der Zeichnung dargestellte Ausführungsbeispiel verdeutlicht. In die stumpf zu verschweißenden Rohre b sind Einsatzrohrstücke α eingesetzt und durch Punktschweißung befestigt, und diese Einsatzstücke sind nach der Schweißstelle hin eingezogen. Die an den Teilen h und α auftretenden Schweißwülste vereinigen sich bei w, so daß hier die besonders kräftige Verbindung entsteht.The method is illustrated by the embodiment shown in the drawing. Insert pipe pieces α are inserted into the pipes b to be butt welded and fastened by spot welding, and these insert pieces are drawn in towards the welding point. The weld beads occurring on parts h and α unite at w, so that the particularly strong connection is created here.
