Abstract
Description
Die Erfindung richtet sich auf eine Orbital-Schweißvorrichtung umfassend wenigstens einen Schweißkopf, welcher mittels einer Antriebs- und Führungseinrichtung zur Ausbildung einer Schweißnaht um ein zu verschweißendes Werkstück bewegbar ist.The Invention is directed to an orbital welding apparatus comprising at least a welding head, which by means of a drive and guide device for training a weld to be welded workpiece is movable.
Schweißtechnisch gesehen gehört das Orbital-Schweißen in der Regel zum teilmechanisierten WIG-Schweißen. Sofern allerdings vorstehend und im Nachfolgenden vom Begriff „Schweißkopf" die Rede ist, muss dieser Begriff im allgemeinsten Sinn verstanden werden, d. h. er deckt sowohl offene als auch geschlossene Schweißköpfe ab und dementsprechend generell auch ganz unterschiedliche Schweißverfahren wie MIGMAG-Schweißen, Microplasma-Schweißen sowie Laserschweißen und ähnliche Verfahren.Technically welding heard heard Orbital welding usually for semi-mechanized TIG welding. If, however, above and in the following the term "welding head" is mentioned, this term must in understood in the most general sense, d. H. he covers both open as well as closed welding heads off and on accordingly, in general, quite different welding methods like MIGMAG welding, Micro plasma welding as well as laser welding and similar Method.
Werden hohe Qualitätsansprüche an die Schweißnaht gestellt, greift man auf das Orbitalschweißen zurück. Primäre Kriterien für den Einsatz der Orbitalschweißtechnik sind, gute Kontrollierbarkeit der Schweißnahtwurzel und Reproduzierbarkeit der Schweißnähte. Auch die Röntgensicherheit und das Schweißen mit dem nur minimal nötigstem Strom sind von großer BedeutungBecome high quality demands placed on the weld, you resort to orbital welding. Primary criteria for the use of Orbital Welding Technology are, good controllability of the weld root and reproducibility of the Welds. Also the x-ray security and welding with only the minimum necessary Electricity is great importance
Chemie, Pharmazie, Lebensmitteltechnik, Biotechnik, Reinstgasanlagen, sind die Hauptsächlichen Einsatzgebiete für die Orbitalschweißtechnik.Chemistry, Pharmaceutical, food technology, biotechnology, pure gas plants, are the main ones Fields of application for the orbital welding technique.
Für die Fertigung von Möbeln oder Geländern findet das Orbitalschweißen wegen der gestalterischen Möglichkeiten der Schweißnähte seine AnwendungFor the production of furniture or railings finds the orbital welding because of the creative possibilities the welds his application
Ein wichtiges Kriterium für das Orbitalschweißen ist die Nahtvorbereitung. In der Regel genügt ein zur Rohrachse rechtwinkliger Sägeschnitt. Überdies sollten die Rohrstöße Grad und Fettfrei sein. Als optimale Nahtvorbereitung hat sich das Planen der Rohrstöße mit sogenannten Plangeräten erwiesen. Durch die Möglichkeit einlagig bis 3mm Wandstärke zuschweißen hat sich das Orbitalschweißen auch als besonders wirtschaftlich erwiesen.One important criterion for the orbital welding is the seam preparation. As a rule, one tube axis is more rectangular Saw cut. moreover should the pipe joints degree and be fat-free. Planing is the optimal preparation for the seam the pipe joints with so-called plan devices proved. By the possibility single layer up to 3mm wall thickness welding shut has orbital welding also proven to be particularly economical.
Ausgehend von den bekannten Vorteilen von Orbital-Schweißanlagen liegt der Erfindung die Aufgabe zu Grunde, diese Schweißtechnik noch weiter zu verbessern und anwenderfreundlicher zu machen.outgoing Of the known advantages of orbital welding systems of the invention the task underlying to further improve this welding technology and to make it more user-friendly.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass an der Antriebs- und Führungseinrichtung wenigstens zwei Schweißköpfe, vorzugsweise in einem Winkel von 180° zueinander, angeordnet sind. Mit Vorteil handelt es sich dabei um zwei WIG-Brenner. Dabei wird jeder einzelne WIG-Brenner in an sich bekannter Weise mit einer gesteuerten Schweißstromquelle verbunden. Optional kann einer der beiden Brenner oder beide Brenner mit einer an sich ebenfalls bekannten automatischen Schweißdrahtzufuhr versehen werden.These Task is inventively characterized solved, that on the drive and guide device at least two welding heads, preferably at an angle of 180 ° to each other, are arranged. Advantageously, these are two TIG torches. Each individual TIG burner is in a known manner with a controlled welding power source connected. Optionally, one of the two burners or both burners with a per se also known automatic welding wire feed be provided.
Zur Herstellung einer 360° Schweißnaht ist dementsprechend lediglich eine Bewegung von ca. 180° erforderlich. Hierdurch wird die Schweißzeit halbiert und wegen der symmetrischen Anordnung die Gefahr eines Verzugs wesentlich reduziert. Da die zu verschweißenden Rohre während des Schweißvorgangs innen mit Formiergas gespült werden, bedeutet eine Halbierung der Schweißdauer nicht nur eine wesentliche Verminderung der Arbeitszeit oder umgekehrt deutliche Erhöhung der Schweißleistung, sondern es kann auch Formier- und Schweißgas eingespart werden.to Making a 360 ° weld is accordingly only a movement of about 180 ° required. This will the welding time halved and due to the symmetrical arrangement the danger of a Delay significantly reduced. Because the pipes to be welded while the welding process flushed with forming gas inside halving the duration of welding is not just an essential one Reduction in working hours or conversely significant increase in Welding performance, but it can also be saved forming and welding gas.
Das erfindungsgemäße Prinzip ist auch bei Rohrinnen-Schweißvorrichtungen sowie bei Sonderkonstruktionen anwendbar.The inventive principle is also with pipe inside welding devices as well as for special constructions applicable.
Nachfolgend wird die Erfindung an Hand eines bevorzugten Ausführungsbeispiels in Verbindung mit der Zeichnung näher erläutert. Diese zeigt eine schematische Darstellung einer erfindungsgemäßen Orbital-Schweißvorrichtung in Schweißposition.following The invention is based on a preferred embodiment explained in connection with the drawing. This shows a schematic Representation of an orbital welding device according to the invention in welding position.
