Abstract
Description
Die Erfindung betrifft ein Verfahren zum Schweißen von metallisch, organisch und anorganisch beschichteten Stahlblechen gleicher oder unterschiedlicher Blechdicke, gleicher oder unterschiedlicher Stahlqualitäten und gleicher oder unterschiedlicher Beschichtungen bzw. beschichteter/unbeschichteter Bleche mit einem Laser-Wolfram-Inertgas-(WIG)- Schweißverfahren, wobei als Laser ein Nd : YAG-Festkörperlaser verwendet wird und der Laserstrahl und der WIG-Lichtbogen in einer Prozeßzone gleichzeitig zusammen als Hybridprozeß den Fügevorgang bewirken (Fig. 1).The invention relates to a method for welding metallic, organic and inorganic coated steel sheets of the same or different sheet thickness, same or different steel qualities and the same or different coatings or coated / uncoated sheets with a laser tungsten inert gas (TIG) welding process, wherein an Nd: YAG solid-state laser is used as the laser and the laser beam and the TIG arc simultaneously effect the joining process in a process zone as a hybrid process ( FIG. 1).
Mit dem Laser-WIG-Schweißen werden im Vergleich zum Laserstrahlschweißen die Produktivität und die Effizienz des Fügeprozesses erhöht, die Investitionskosten pro Ausgangsleistung gesenkt und Prozeßsicherheit und Nahtqualität gesteigert, was auf verschiedene physikalische Effekte zurückzuführen ist.Laser TIG welding is compared to laser beam welding Productivity and the efficiency of the joining process increases the investment costs per Output power reduced and process reliability and seam quality increased, which on various physical effects can be attributed.
Ein Laserstrahl (1) erzeugt eine Dampfkapillare (3) im Werkstück, welches vom Lichtbogen (2) eines WIG-Brenners (7) überdeckt wird. Der Lichtbogen (2) hat eine größere Ausdehnung als die Dampfkapillare (3), weshalb nur ein Teil der Lichtbogenenergie in die Dampfkapillare (3) eingekoppelt werden kann. Somit wirkt der Lichtbogen (2) überwiegend als Oberflächenwärmequelle, die der Schweißnaht eine typische kelchförmige Gestalt gibt. Lichtbogenströmung und Lichtbogendruck übertragen einen Impuls auf die Schmelzbadoberfläche, wodurch die Schmelzbaddynamik erleichtert und verstärkt wird. Die effektive Blechdicke wird durch die entstehende Mulde reduziert und die Lasereinkopplung verbessert, weshalb die Schweißgeschwindigkeit erhöht und die Produktivität verbessert wird. Eine Führung des Lichtbogens (2) durch den Laserstrahl (1) tritt dadurch ein, daß der Lichtbogen (2) den energetisch günstigsten Zustand annimmt, indem er auf dem Fußpunkt des Laserstrahls (Ansatz der Dampfkapillare, umgebende Schmelzzone) brennt. Somit müssen Laserstrahl (1) und Elektrodenspitze nicht exakt positioniert sein, um einen Hybridprozeß zu ermöglichen. Insbesondere bei dreidimensionalen Fügeaufgaben entfallen dadurch zusätzliche Positionierachsen und ermöglichen einen kostengünstigen, reproduzierbaren Prozeß bei hoher Schweißnahtqualität.A laser beam ( 1 ) creates a steam capillary ( 3 ) in the workpiece, which is covered by the arc ( 2 ) of a TIG torch ( 7 ). The arc ( 2 ) has a larger extension than the steam capillary ( 3 ), which is why only part of the arc energy can be coupled into the steam capillary ( 3 ). The arc ( 2 ) thus mainly acts as a surface heat source, which gives the weld seam a typical goblet shape. Arc flow and arc pressure transmit an impulse to the melt surface, which facilitates and strengthens the melt dynamics. The effective sheet thickness is reduced by the resulting trough and the laser coupling is improved, which is why the welding speed is increased and productivity is improved. The arc ( 2 ) is guided by the laser beam ( 1 ) in that the arc ( 2 ) assumes the most energetically favorable state by burning at the base of the laser beam (approach of the steam capillary, surrounding melting zone). Thus, the laser beam ( 1 ) and the electrode tip do not have to be positioned exactly in order to enable a hybrid process. In particular for three-dimensional joining tasks, this eliminates the need for additional positioning axes and enables a cost-effective, reproducible process with high weld quality.
Beim Lichtbogenschweißen können im Vergleich zum Laser-WIG-Schweißen nur erheblich geringere Schweißgeschwindigkeiten realisiert werden, beim Laserstrahlschweißen ist bei gleicher Schweißgeschwindigkeit und sicherer Durchschweißung ein erheblich größerer Gesamtenergieeinsatz aufgrund des sehr geringen Wirkungsgrades von Laserstrahlquellen als beim Laser-WIG-Verfahren erforderlich. Die am Werkstück für den Fügeprozeß notwendige Energie wird beim Laser-WIG-Verfahren einerseits durch den Laserstrahl, andererseits durch den Lichtbogen zu Verfügung gestellt, wobei der Wirkungsgrad einer Lichtbogenschweißmaschine erheblich höher ist und somit der Gesamtenergieeinsatz für den Fügeprozeß im Vergleich zum Laserstrahlschweißen erheblich reduziert wird. Darüberhinaus ist bei gleicher Gesamtleistung am Werkstück eine Laserstrahlquelle mit geringerer Leistung für den Fügeprozeß ausreichend. Die Investitionskosten für eine Laserstrahlquelle sind stark leistungsabhängig und um Größenordnungen höher als für eine Lichtbogenschweißstrom quelle. Der Kostenvergleich zwischen konventionellem Laserstrahlschweißen und Laser-WIG-Schweißen führt zu geringeren Produktionskosten und geringeren Investitionskosten für das Laser-WIG-Schweißverfahren.Arc welding can only do a lot compared to laser TIG welding lower welding speeds can be realized with laser beam welding same welding speed and safe welding through a significantly larger Total energy use due to the very low efficiency of laser beam sources required for the laser TIG process. The parts necessary for the joining process In the laser TIG process, energy is generated on the one hand by the laser beam and on the other hand by provided the arc, the efficiency of a Arc welding machine is significantly higher and thus the total energy input for the Joining process is significantly reduced compared to laser beam welding. Furthermore is a laser beam source with lower power for the same total power on the workpiece sufficient for the joining process. The investment costs for a laser beam source are high performance-dependent and orders of magnitude higher than for an arc welding current source. The cost comparison between conventional laser beam welding and laser TIG welding leads at lower production costs and lower investment costs for the laser TIG welding process.
Die Vorteile des Laser-WIG-Verfahrens liegen im kostengünstigen Hybridprozeß und in der besseren Spaltüberbrückbarkeit beim Fügeprozeß aufgrund der kelchförmigem Nahtgestalt. Bisher wurde das Laser-WIG-Verfahren zum Schweißen von Aluminumlegierungen und unbeschichteten Stählen in Forschungseinrichtungen entwickelt und untersucht. Aufgrund der widersprüchlichen Ergebnisse bezüglich der Durchführbarkeit eines derartigen Hybridprozesses (z. B. H. Cui: "Untersuchung der Wechselwirkung zwischen Schweißlichtbogen und fokussiertem Laserstrahl und der Anwendungsmöglichkeiten kombinierter Laser-Lichtbogentechnik" Dissertation TU Braunschweig 1991, C. Maier, J. Beersiek, J. Neuenhahn, K. Behler, E. Beyer: "Kombiniertes Lichtbogen-Laserstrahl-Schweiß verfahren - Online-Prozeßüberwachung" DVS-Berichte Bd. 170 1995 S. 45-51, I. Decker, J. Wendelstorf, H. Wohlfahrt: "Laserstrahl-WIG-Schweißen von Aluminiumlegierungen" DVS-Berichte Bd. 170 1995 S. 96-99), insbesondere zum Fügen von Stählen, ist eine Umsetzung in die industrielle Produktion bislang nicht erfolgt. Die Entwicklung eines kontinuierlichen und reproduzierbaren Prozesses für beschichtete Stahlbleche wurde durch folgende Randbedingungen behindert: a) Für den Laser-WIG-Pro zeß wurden aufgrund der höheren technisch verfügbaren Leistung im continous-wave- Betrieb CO2-Laser eingesetzt (max. Leistung bis 40 kW), 1998 war der erste Nd : YAG-Fest körperlaser mit 4 kW Laserstrahlleistung am Werkstück erhältlich. Abgesehen von der höheren Strahlqualität eines Festkörperlasers, besteht der wesentliche Unterschied der beiden Strahlerzeugerarten für den Laser-WIG-Prozeß in der Ausbildung einer Plasmazone über der Dampfkapillaren, die beim Festkörperlaser im Vergleich zum CO2-Laser sehr klein ist. Bei einer größeren Ausdehnung des Plasmas kommt es beim Hybridprozeß zu Wechselwirkungen mit dem Lichtbogen und der Lichtbogen kann gelöscht werden, so daß ein kontinuierlicher Prozeß nicht reproduzierbar möglich ist. b) Bei metallisch beschichteten Blechen, z. B. verzinkten Stahlblechen, treten auf Grund der niedrigen Schmelz- und Verdampfungstemperatur der Beschichtung Poren in der Schweißverbindung auf, die bei ausreichender Anzahl und ungünstiger Verteilung die mechanischen Eigenschaften negativ beeinflussen. Bedingt durch die hohe Geschwindigkeit des Fügeprozesses können die Gasblasen nicht aus der Schmelze entweichen, werden durch die schnell fortschreitende Erstarrungsfront überholt und als Poren in der Schweißnaht "eingefroren". c) Der in organischen Beschichtungen enthaltene Kohlenstoff kann durch den thermischen Fügeprozeß in das Schweißbad gelangen und resultiert nach der Erstarrung aufgrund des erhöhten Kohlenstoffgehaltes im Schweißgut des Stahls in einer Aufhärtung der Naht, wodurch die für Taylored Blanks zwingend erforderliche Umformbarkeit eingeschränkt wird. The advantages of the laser TIG process lie in the inexpensive hybrid process and in the better gap bridging in the joining process due to the cup-shaped seam shape. So far, the laser TIG process for welding aluminum alloys and uncoated steels has been developed and investigated in research facilities. Due to the contradictory results regarding the feasibility of such a hybrid process (e.g. BH Cui: "Investigation of the interaction between welding arc and focused laser beam and the possible applications of combined laser arc technology" dissertation TU Braunschweig 1991, C. Maier, J. Beersiek, J. Neuenhahn, K. Behler, E. Beyer: "Combined arc laser beam welding process - online process monitoring" DVS reports vol. 170 1995 pp. 45-51, I. Decker, J. Wendelstorf, H. Wohlfahrt: "Laser beam TIG -Welding of aluminum alloys "DVS reports Vol. 170 1995 pp. 96-99), especially for joining steels, has not yet been implemented in industrial production. The development of a continuous and reproducible process for coated steel sheets was hampered by the following boundary conditions: a) CO 2 lasers were used for the laser TIG process due to the higher technically available power in continous-wave operation (max. Power up to 40 kW), in 1998 the first Nd: YAG solid-state laser with 4 kW laser beam power was available on the workpiece. Apart from the higher beam quality of a solid-state laser, the main difference between the two types of beam generators for the laser TIG process is the formation of a plasma zone above the vapor capillaries, which is very small in the solid-state laser compared to the CO 2 laser. With a larger expansion of the plasma, the hybrid process interacts with the arc and the arc can be extinguished, so that a continuous process is not reproducible. b) In the case of metal-coated sheets, e.g. B. galvanized steel sheets occur due to the low melting and evaporation temperature of the coating pores in the welded joint, which adversely affect the mechanical properties with a sufficient number and unfavorable distribution. Due to the high speed of the joining process, the gas bubbles cannot escape from the melt, are overtaken by the rapidly progressing solidification front and "frozen" as pores in the weld seam. c) The carbon contained in organic coatings can get into the weld pool through the thermal joining process and, after solidification, results in hardening of the seam due to the increased carbon content in the weld metal of the steel, as a result of which the formability required for Taylored blanks is restricted.
Die Erfindung ermöglicht ein Verfahren zum Fügen beschichteter Stahlbleche derart, daß ein sicherer und reproduzierbarer Schweißprozeß zum Fügen metallisch und organisch beschichteter Stahlbleche bei sehr guter Schweißnahtqualität in einem großen Parameterfenster möglich ist. Dazu sind folgende Randbedingungen zu erfüllen (Fig. 2-4): (ϕWIG = 30°-45° (9), lV = 6 mm-10 mm (10), hL = ± 4 mm (11), ζWIG = 75°-105° (12), lB90° = 0,2 mm-3 mm (13), bs = 0 mm-0,2 mm (14), ζL = 75°-105° (15), lh 0,5 mm-2 mm (16), Lfx = 0 mm-2 mm (17), Lfy = ± 0,3 mm (18), Lfz = ± 4 mm (19), γ = 30°-150° (20), dD = 8 mm-30 mm (21), dE = 1 mm-6,4 mm (22), ds = 0,4 mm-5 mm (23), IWIG = 50 A-350 A, PLaser = 1 kW-4 kW, VGas = 20 l/min-80 l/min He, die wahre Lichtbogenlänge ergibt sich zu lwahr = lB90/cos ϕWIG.The invention enables a method for joining coated steel sheets in such a way that a safe and reproducible welding process for joining metallic and organic coated steel sheets with very good weld seam quality is possible in a large parameter window. The following boundary conditions must be met ( Fig. 2-4): (ϕ TIG = 30 ° -45 ° ( 9 ), l V = 6 mm-10 mm ( 10 ), h L = ± 4 mm ( 11 ), ζ TIG = 75 ° -105 ° ( 12 ), l B90 ° = 0.2 mm-3 mm ( 13 ), b s = 0 mm-0.2 mm ( 14 ), ζ L = 75 ° -105 ° ( 15 ), l h 0.5 mm-2 mm ( 16 ), Lf x = 0 mm-2 mm ( 17 ), Lf y = ± 0.3 mm ( 18 ), Lf z = ± 4 mm ( 19 ), γ = 30 ° -150 ° ( 20 ), d D = 8 mm-30 mm ( 21 ), d E = 1 mm-6.4 mm ( 22 ), d s = 0.4 mm-5 mm ( 23 ), I TIG = 50 A-350 A, P Laser = 1 kW-4 kW, V Gas = 20 l / min-80 l / min He, the true arc length results in l true = l B90 / cos ϕ TIG .
Die Vorteile der Erfindung liegen in der Anwendung des kostengünstigen Laser-WIG-Pro zesses auf beschichtete Stahlbleche und in der hohen Nahtqualität trotz der Beschichtungen der Bleche, die bei herkömmlichen Verfahren zu Ungänzen in der Schweißnaht führen können und die mechanisch-technologischen Eigenschaften der Schweißverbindung herabsetzen können. Weitere Vorteile sind die Möglichkeiten, Stahlbleche mit gleichen oder unterschiedlichen metallischen (z. B. verzinkt), organischen (z. B. Bonazinc 3000™) oder anorganischen (z. B. phosphatiert, cyanokadmiert) Beschichtungen bei gleichen oder unterschiedlichen Stahlqualitäten (z. B. DC 05 an Z StE 340) und gleichen oder unterschiedlichen Blechdicken miteinander zu verschweißen. The advantages of the invention lie in the use of the inexpensive Laser-TIG-Pro zesses on coated steel sheets and in high seam quality despite the Coatings of the sheets that are inconsistent in the conventional process Can lead weld seam and the mechanical-technological properties of the Can reduce weld connection. Other advantages are the possibilities Steel sheets with the same or different metallic (e.g. galvanized), organic (e.g. Bonazinc 3000 ™) or inorganic (e.g. phosphated, cyanocadmated) Coatings with the same or different steel qualities (e.g. DC 05 on Z StE 340) and the same or different sheet thicknesses to be welded together.
