Description
Verfahren und Vorrichtung zum unlösbaren Verbinden von Bauteilen aus wärmeschmelzbarem, metallischen Werkstoff Method and device for non-detachable joining of components of heat-fusible metallic material
Die Erfindung bezieht sich auf ein Verfahren zum unlösbaren Verbinden von Bauteilen aus wärmeschmelzbarem, metallischen Werkstoff, mit einer robotergeführten Schweißeinheit zur Ausführung eines Hybridschweißprozesses.The invention relates to a method for the non-detachable joining of components made of heat-fusible, metallic material, with a robot-guided welding unit for performing a hybrid welding process.
Die Erfindung bezieht sich auch auf eine Vorrichtung zur Durchführung des vorstehend angegebenen Verfahrens.The invention also relates to an apparatus for carrying out the method specified above.
Verfahren und Vorrichtungen der vorbezeichneten Gattung finden unter anderem industrielle Anwendung beim Fügen von Dickblech, wie es insbesondere im Schiffbau eingesetzt wird.Methods and devices of the type mentioned above find, inter alia, industrial application in the joining of thick sheet metal, as it is used in particular in shipbuilding.
Es hat sich gezeigt, daß ein reines Laser-Hybridschweißen, eine Kombination aus Laserschweißen und Metall-Schutzgas-Schweißen (MSG) bei Dickblechen von zum Beispiel 15 mm, zur Entstehung eines sogenannten „Mittelrippendefektes" führt, der meist auf ein Heißrißproblem, zurückzuführen ist. Die Schweißnaht muß, besonders bei großen Blechdicken von zum Beispiel 15 mm und mehr, aufgrund der auftretenden Heißrißprobleme nachgeschweißt werden. Das zusätzliche Nachschweißen ist zumeist ein Unterpulver-Schweißverfahren.
Das Nachschweißen der Hybridnaht, vor allem das Nachschweißen imIt has been found that pure laser hybrid welding, a combination of laser welding and metal inert gas welding (MSG) with thick plates of, for example, 15 mm, leads to the formation of a so-called "midrib defect", which is mostly due to a hot cracking problem The weld must be rewelded, especially with large sheet thicknesses of, for example, 15 mm and more, due to the hot cracking problems that occur. The rewelding of the hybrid seam, especially the rewelding in the
Unterpulver-Verfahren, hat den Nachteil, daß die Gefahr der Verlagerung des Mittelrippendefektes in den Wurzelbereich der Hybridnaht besteht. Das kann bedeuten, daß auch die Wurzel der bereits durch das Unterpulver-Verfahren nachgearbeiteten Schweißnaht ebenfalls nachgeschweißt werden muss. Dies erfordert noch einmal weitere Arbeitsschritte, nämlich das bereits geschweißte Stück muss gewendet und die Naht noch einmal, nunmehr an ihrer anderen Seite, geschweißt werden.Submerged powder method, has the disadvantage that there is a risk of shifting the midrib defect in the root area of the hybrid seam. This may mean that also the root of the already reworked by the sub-powder method weld must also be rewelded. This requires further work steps, namely, the already welded piece must be turned and the seam again, now on its other side, welded.
Das zum Nachschweißen eingesetzte Unterpulver-Verfahren hat außerdem auch noch den Nachteil, daß die Wärmeeinbringung in das Dickblech und damit sein Verzug nicht unbeachtlich ist.The submerged powder method used for rewelding also has the disadvantage that the heat input into the thick sheet and thus its distortion is not insignificant.
Des weiteren ist eine durch das Unterpulver-Schweißverfahren gebildete Nahtüberhöhung stark ausgeprägt, was insbesondere im Schiffbau, dort imFurthermore, a seam superimposition formed by the submerged-arc welding process is pronounced, which is particularly true in shipbuilding, there in the
Außenhautbereich, als optisch unvorteilhaft angesehen wird.Outer skin area, as optically unfavorable.
Der Erfindung liegt die Aufgabe zugrunde, die Rißbildungsgefahr, daß heißt die Entstehung von Mittelrippendefekten, beim Hybridschweißen von Dick- blechen zu vermeiden.The invention has for its object to avoid the risk of cracking, that is, the formation of Mittelrippendefekten, the hybrid welding of thick sheets.
Diese Aufgabe ist verfahrensmäßig durch die Merkmale des Patentanspruchs 1 gelöst. Die Ausgestaltungen des erfindungsgemäßen Verfahrens ergeben sich aus den Unteransprüchen 2 bis 5.This object is procedurally achieved by the features of claim 1. The embodiments of the method according to the invention will become apparent from the dependent claims 2 to 5.
Vorrichtungsmäßig ist die der Erfindung zugrunde liegende Aufgabe durch die Merkmale der Ansprüche 6 bis 8 gelöst.Device-wise, the object underlying the invention is achieved by the features of claims 6 to 8.
Bei dem erfindungsgemäßen Verfahren zum unlösbaren Verbinden von Bau- teilen aus wärmeschmelzbarem, metallischen Werkstoff wird eine robotergeführte Schweißeinheit zur Ausführung eines Hybridschweißprozesses eingesetzt. Erfindungsgemäß wird, in einem vorbestimmten Abstand dem Hybridschweißprozeß folgend, ein Metall-Aktiv-Gas-Hoch-Leistungs-Schweißprozeß (MAG-HL) ausgeführt.
Sobald die Schweißnaht des vorangehenden Hybridschweißprozesses anfängt sich abzukühlen, folgt bereits der nachfolgende, erfindungsgemäß zusätzliche MAG-HL-Prozeß, mit dem die Risse beseitigt werden.In the method according to the invention for the non-detachable connection of components of heat-fusible, metallic material, a robot-controlled welding unit is used for carrying out a hybrid welding process. According to the invention, a metal active gas high power welding process (MAG-HL) is performed at a predetermined distance following the hybrid welding process. As soon as the weld of the preceding hybrid welding process begins to cool, the following, according to the invention, additional MAG-HL process with which the cracks are eliminated already follows.
Ein Hybrid-Schweißprozeß kann jede Kombination verschiedener Schweißprozesse sein.A hybrid welding process can be any combination of different welding processes.
Mit besonderem Vorteil wird zur Ausführung des Hybridschweißprozesses ein Metall-Schutzgas-Schweißprozeß (MSG) in Kombination mit einemWith particular advantage, the execution of the hybrid welding process, a metal-shielding gas welding process (MSG) in combination with a
Laserschweiß-prozeß vorgenommen. Derartige Laser-Hybridschweißprozesse bieten im wesentlichen wirtschaftliche Vorteile, da ein Einlagenschweißen inLaser welding process made. Such laser hybrid welding processes offer substantially economic advantages, since deposit welding in
Verbindung mit der Einsparung zusätzlicher Nahtfugenvorbereitung möglich ist, wodurch besonders bei größeren Blechdicken Einseitenschweiß- technologien umgesetzt werden können, insbesondere an solchen Bauteilen, bei denen keine Zugängigkeit der Gegenseite des Schweißstoßes besteht, wie es im Schiffbau häufig vorkommt.Connection with the saving of additional seam joint preparation is possible, whereby Einseitenschweiß- technologies can be implemented especially for larger sheet thicknesses, especially on those components where there is no accessibility of the opposite side of the weld joint, as is common in shipbuilding.
Der den MAG-HL-Schweißprozeß ausführende Brenner ist mit Vorteil an einer Baueinheit angeordnet, die von der robotergeführten Schweißeinheit zurThe torch carrying out the MAG-HL welding process is advantageously arranged on a structural unit that extends from the robot-guided welding unit to the
Ausführung des Hybridschweißprozesses getragen und mitgeführt wird.Carried the execution of the hybrid welding process and carried.
Hybridschweißprozeß und nachfolgender MAG-HL-Schweißprozeß werden demzufolge mit gleicher Schweißgeschwindigkeit entlang einer Naht ausgeführt, womit das erfindungsgemäße Verfahren auch als „Tandem- Schweißverfahren" bezeichnet werden kann.Hybrid welding process and subsequent MAG-HL welding process are therefore carried out at the same welding speed along a seam, so that the inventive method can also be referred to as a "tandem welding process".

Der an der Ausführung des Metall-Aktiv-Gas-Hoch-Leistungs-Schweißprozeß (MAG-HL) beteiligte Brenner wird an der Schweißeinheit stechend geführt. Diese Ausrichtung des vorlaufenden MSG-Brenners als geschleppter Brenner
und des nachlaufenden MAG-HL- Brenners als stechend geführt, erlaubt optimale Schweißergebnisse bei hohen Schweißgeschwindigkeiten.The burner involved in the execution of the metal-active-gas-high-power welding process (MAG-HL) is guided stingingly at the welding unit. This orientation of the leading MSG burner as a towed burner and the trailing MAG-HL torch as piercing, allows optimum welding results at high welding speeds.
Bei Blechdicken von circa 13 bis 22 mm erfolgt mit dem erfindungsgemäßen Verfahren eine fehlerfreie, zweilagige Schweißung in einer einzigen Fahrt der robotergeführten Schweißeinheit, welche die zweiten Brenner führende Baueinheit zusätzlich trägt. Es hat sich gezeigt, daß bei Blechdicken von 18 bis 20 mm Dicke ein Abstand zwischen Schweißeinheit und Baueinheit von etwa 150 bis 400 mm, je nach Schweißgeschwindigkeit, vorteilhaft ist. Bei zum Beispiel 18 mm starken Blechen werden durch das vorgeschaltete Laser-At sheet thicknesses of about 13 to 22 mm is carried out with the inventive method an error-free, two-ply welding in a single ride the robot-controlled welding unit, which additionally carries the second burner leading assembly. It has been shown that for sheet thicknesses of 18 to 20 mm thickness, a distance between the welding unit and assembly of about 150 to 400 mm, depending on the welding speed, is advantageous. For example, with 18 mm thick sheets, the upstream laser
Hybridverfahren die unteren 8 mm der Fuge aufgefüllt und der nachgeschaltete MAG-H L-Prozeß füllt den Rest der Fuge mit einem Fülldraht von 1 ,6 mm Durchmesser auf. Um bei den genannten, relativ hohen Geschwindigkeiten den Draht aufzuschmelzen und einen ausreichenden Füllgrad zu erreichen, ist ein entsprechendes Hochleistungsschweißgerät einzusetzen.Hybrid method filled the bottom 8 mm of the joint and the downstream MAG-H L process fills the rest of the joint with a filler wire of 1, 6 mm diameter. In order to melt the wire at the said, relatively high speeds and to achieve a sufficient degree of filling, a corresponding high-performance welding device is to be used.
