Description
Bisher wurden an die Außenhaut- und Decks-Beplattungen, Doppelboden, Schotten, Bodenwrangen, Stringer, Randplatten usw. die sie versteifenden Bauteile unmittelbar angeschweißt. Die Verschweißung wurde dabei entsprechend dem unmittelbaren Aufsetzen der Versteifungsbauteile durch sogenannte Kehlnähte vorgenommen.So far, the outer skin and deck plating, double floor, bulkheads, Floor walls, stringers, edge plates, etc. are welded directly to the stiffening components. The welding was carried out in accordance with the immediate placement of the stiffening components using so-called Fillet welds made.
Diese Ausführung mit Kehlen führte zu Bedenken hinsichtlich der verschiedenartigen Einwirkungen des Schweiß Vorganges auf die Platten dieser Schiffsteile, indem Schrumpfspannungen, Gefügeveränderungen, Verminderung der berechneten Querschnitte, ferner eine Verminderung der Widerstandskraft gegen Wechsel- und dynamische Beanspru-This fillet design raised concerns about the various Effects of the welding process on the plates of these ship parts by reducing shrinkage stresses, Structural changes, reduction of the calculated cross-sections, furthermore a reduction of the drag force against alternating and dynamic stress
a chung usw. der Platten entstanden, die die Güte der Ausführung, den Arbeitsgang, die Festigkeit des Schiffskörpers usw. ungünstig beeinflußten. Außerdem war es bei dem unmittelbaren Aufschweißen der Versteifungsbauteile auf die Platten nicht möglich, auch automatische Stumpfschweißung anzuwenden und so die Massenherstellung der in Frage stehenden Schweißnähte zu erleichtern. Dabei war es bekannt, rippenförmige Schweißansätze an Bauteilen vorzusehen, an die andere Bauteile angeschweißt werden sollten, z. B. an Winkelstücken, T-Stücken, Zylindern von Vierbrennungskraftmaschinen o. dgl.a chung etc. of the panels were created, which the quality of the execution, the work process, the Strength of the hull, etc. adversely affected. Besides, it was with the immediate one It is not possible to weld the stiffening components onto the plates; automatic butt welding can also be used and so facilitate the mass production of the welds in question. Included it was known to provide rib-shaped welds on components to the other components should be welded, e.g. B. on elbows, T-pieces, cylinders of four-combustion engines o.
Dies geschah, um Schrumpfspannungen und ähnliche ungünstige durch das Schweißen entstehende Einflüsse zu vermeiden. Andererseits war es auch im Schiffbau bekannt, Beplattungen mit Rippen im Walzprozeß zu versehen, an die Versteifungen angeschweißt werden konnten.This was done in order to avoid shrinkage stresses and the like unfavorable caused by the welding Avoid influences. On the other hand, it was also known in shipbuilding, plating to be provided with ribs in the rolling process to which stiffeners could be welded.
Die Versteifungen standen dabei mit ihrer Längsachse senkrecht zu den Rippen, die die eigentlichen Plattenversteifungen bildeten,und dienten zur Abstützung der Platten gegen andere Bauteile. Die Rippen hatten nicht die Aufgabe, die Platte beim Anschweißen der Versteifungsenden vor Schweißeinflüssen zu schützen. Der Erfindung liegt der Gedanke zugrunde, die bekannten Schweißansätze in ihrer Ausbildung schiffbaulichen Verhältnissen so anzupassen, daß sie zum Anschweißen der Versteifungen, wie Spanten o. dgl., an die zu versteifenden Schiffswandungen verwendbar werden.The stiffeners stood with their longitudinal axis perpendicular to the ribs that the actual plate stiffeners formed and served to support the plates against other components. The ribs did not have the task of welding the plate on To protect stiffening ends from the effects of perspiration. The idea lies in the invention based on the well-known welding approaches in their training shipbuilding conditions adapt so that they can be used to weld the stiffeners, such as frames or the like the ship walls to be stiffened can be used.
Erfindungsgemäß sind bei einer Schweißverbindung zwischen Beplattung und den sie versteifenden Bauteilen für Schiffe oder ähnliche große Schwimmkörper, bei der die Versteifungen an beim Walzen hergestellten Rippen der Platte angeschweißt sind, die Rippen als in Längsrichtung der anzuschweißenden Versteifungen angeordnete Schweißansätze nur solcher Höhe ausgebildet, daß einerseits Korn ver änderungen und Schwächungen des Querschnitts der Platten durch das SchweißenAccording to the invention are in a welded connection between the plating and they stiffening components for ships or similar large floating bodies, in which the stiffeners are welded to ribs of the plate produced during rolling, the ribs than in the longitudinal direction of the to be welded Stiffeners arranged welding lugs only formed such a height that on the one hand Grain changes and weakening of the cross-section of the plates as a result of welding
vermieden werden, andererseits Stumpfschweißung zum Anschluß der \rersteifungen anwendbar ist.be avoided, and, butt welding is applicable to connect the \ r ersteifungen.
Bei dieser Ausbildung wird es möglich, 'äfe\ im Schiffbau beim Anschweißen der Versteh" fungen an ihre Platten vorkommenden, insgesamt sehr langen Schweißstrecken durch automatische Stumpfschweißung in kürzerer und schweißtechnisch einwandfreier Weise als bisher zu bewältigen.In this configuration, it is possible to 'AEFE \ shipbuilding during welding of Understanding "levies occurring on their plates to handle overall very long welding lines by automatic butt in less perspiration and technically sound manner than before.
Die Erfindung ist beispielsweise und schematisch in der beiliegenden Zeichnung veranschaulicht, und es stellt dar:The invention is illustrated by way of example and schematically in the accompanying drawing, and it represents:
