Für Knotenpunkte sind Muffenverbindungen bekannt? ferner Verbindungen, bei denen das eine anzuschweissende Rohr der Rundung des anderen durch Fräsen angepasst wird, ferner auch solche, bei denen ein Knotenblech die Verbindung zwischen den Rohren bildet* Alle diese Ausführungen sind teuer und umständlich JDemgegenüber werden erfindungsgemäss die Rohrenden der anzuschweissenden Rohre in einen Arbeitsgang gleichzeitig maschinell zusammengedrückt und abgeschert, wobei ζβΒβ eine Form nach Abb. 1 (Ansicht) und Abb,2 (Seitenansicht) entsteht. Hierdurch ergibt sich erstens für die öchweissverbindung nach Abb. 3» Querschnitt nach Abb. 4,eine verbreiterte Rohrauflage in der einen Richtung, wodurch das Widerstandsmoment an der Schweissstelle vergrössert wird, zweitens werden beim Anfügen an das durchlaufende Rohr Kehlen gebildet, die das Schweissen von V-Nähten ermöglichen. Auch Schrägstreben und Winkelstrebeiij, Abb. 5 und 6, sind leicht herstellbar und ergeben technisch günstige und billige Rohrverbindungen.Are socket connections known for junctions ? Further, compounds in which the one to be welded tube of the rounding of the other is adjusted by milling, and also those in which a gusset plate forms the connection between the tubes * All of these designs are expensive and cumbersome J In contrast, according to the invention, the tube ends of the part to be welded pipes in one operation simultaneously compressed and sheared by machine, whereby ζ β Β β a shape according to Fig. 1 (view) and Fig, 2 (side view) is created. This results, firstly, for the welded joint according to Fig. 3 »cross section according to Fig. 4, a widened pipe support in one direction, which increases the moment of resistance at the welding point Enable V-seams. Inclined struts and angle struts, Fig. 5 and 6, are easy to manufacture and result in technically favorable and inexpensive pipe connections.
