Die vorliegende Erfindung betrifft eine Abänderung des Verfahrens nach Patentanmeldung U 4034 VIIId/ 21h.The present invention relates to a modification of the method according to patent application U 4034 VIIId / 9pm.
Das Verfahren gemäß dieser Patentanmeldung dient dem Erhitzen, Schmelzen, Schweißen, Schneiden u. dgl. eines den elektrischen Strom leitenden Werkstücks unter Anwendung einer mittels Hilfslichtbogen zündbaren Lichtbogenentladung zwischen einer Stabelektrode und dem Werkstück, wobei die Bogenentladung in einer zwischen Elektrode und Werkstück angeordneten Düse eingeschnürt und fokussiert wird und die Einschnürung der Lichtbogensäule zur Erzielung eines gegenüber dem nicht eingeschnürten Lichtbogen erhöhten Spannungsabfalls je Längeneinheit bewirkt wird durch das an sich bekannte Hindurchblasen eines hierbei aber in den Lichtbogen eintretenden und ihn stützenden Gasstroms, wobei die Einschnürung der Plasmasäule dem Wärmebedarf hinsichtlich Aufschmelzung bzw. Verdampfung des Werkstoffes des Werkstückes an der Arbeitsstelle angepaßt wird durch die an sich bekannte Wahl des Düsendurchmessers und/oder durch Regelung der durchströmenden Gasmenge je Zeiteinheit.The method according to this patent application is used for heating, melting, welding, cutting and the like of an electric current conductive workpiece using an auxiliary arc ignitable arc discharge between a stick electrode and the workpiece, whereby the arc discharge is constricted and focused in a nozzle arranged between the electrode and the workpiece and the constriction of the arc pillar to achieve an opposite to the non-constricted Arc increased voltage drop per unit length is caused by blowing through, which is known per se a gas flow entering the arc and supporting it, wherein the Constriction of the plasma column the heat demand with regard to melting or evaporation of the Material of the workpiece is adapted to the job by the known choice of Nozzle diameter and / or by regulating the amount of gas flowing through per unit of time.
Es wurde nun gefunden, daß es möglich ist und eine Reihe von Sondervorteilen bietet, dieses Verfahren der Erzeugung und Anwendung eines sogenannten Plasmastrahles hoher Wärmeintensität, großer Stabilität auch bei größerer Länge und die. betreffenden Vorrichtungen erfindungsgemäß dadurch abzuändern, daß als Elektrode in an sich bekannter Weise eine abschmelzende Drahtelektrode verwendet wird.It has now been found that it is possible and offers a number of special advantages to use this method of Generation and application of a so-called plasma jet of high heat intensity, great stability even with greater length and the. relevant devices according to the invention to be modified in that as Electrode in a manner known per se, a consumable wire electrode is used.
Es war zunächst nicht zu erwarten, daß das mit einem Gaslichtbogen betriebene Verfahren nach der Hauptpatentanmeldung ebenso auch mit einem Metalldampflichtbogen betrieben werden kann, und war ferner unter anderem nicht zu erwarten, daß das zusammen mit dem hindurchblasenden Gasstrom durch die einengende Düse getriebene geschmolzene Metall der Drahtelektrode dem einengenden Düsendurchtritt weder beschädigt noch verstopft. Das gemäß der "Hauptpatentanmeldung mit einem Plasmastrahl hoher Wärmeintensität, großer Länge und Stabilität arbeitende Verfahren ist daher nach der vorliegenden Erfindung z. B. auch zum schnellen Schweißen mit starken Strömen insbesondere verhältnismäßig dicker Metallkörper möglich und sehr vorteilhaft, unter anderem auch, weil die Düse ein Auswandern des Bogens \'erhindert. Das Verfahren läßt sich ebenso vorteilhaft zum Schneiden anwenden.Initially, it was not to be expected that the gas arc operated process would work according to the Main patent application can also be operated with a metal vapor arc, and was further among other things not to be expected that this together with the gas stream blowing through the constricting nozzle expelled molten metal of the wire electrode to the constricting nozzle passage neither damaged nor clogged. That according to the "main patent application with a plasma jet higher Heat intensity, long length and stability working method is therefore in accordance with the present Invention z. B. also for fast welding with strong currents, in particular relatively thicker Metal body possible and very advantageous, among other things because the nozzle causes the Bow \ 'diminished. The method can also be used advantageously for cutting.
Die in üblicher Weise zugeführte Elektrode, z. B. aus abschmelzendem Draht, wird vorzugsweise in den eingeschnürten Durchtritt der Düse geleitet und mittels der Wärme des Lichtbogens dort geschmolzen. Das geschmolzene Metall wird dann in Form ein-Verfahren zum Schweißen,The electrode supplied in the usual way, e.g. B. from melting wire, is preferably in the constricted passage of the nozzle and melted there by means of the heat of the arc. The molten metal is then in the form of a welding process,

zelner, voneinander getrennter Tröpfchen zusammen mit dem Lichtbogen und dem treibenden Gas weiter durch die Düse hindurch auf das Werkstück übergeführt. individual, separated droplets along with the arc and the propellant gas transferred through the nozzle onto the workpiece.
Bekannt ist aus einer Druckschrift ein Lichtbogenschweißbrenner, der für den Lichtbogen einen langen, verhältnismäßig engen Kanal mit einer einschnürenden Düse am Ende besitzt, die an dem einen Pol liegt, und ferner eine an dem anderen Pol liegende Elektrode aufweist und wobei entlang der Elektrode Gas strömt, so daß der Lichtbogen sowohl innerhalb des Kanals als auch anschließend und noch stärker in der Düse verengt wird, mithin angenommen werden muß, daß der Lichtbogen die bekannten Eigenschaften des eingeschnürten Bogens, insbesondere eine erhöhte Stromdichte und einen erhöhten Spannungsabfall je Längeneinheit annimmt. In der Druckschrift wird jedoch nicht offenbart, daß speziell bei einem solchen Plasmastrahl eine abschmelzende Elektrode verwendet werden soll, vielmehr ist dort noch ein Brenner zum Schweißen mit einer hohlen Elektrode beschrieben, durch die hindurch ein am Lichtbogen abschmelzender Metalldraht zugeführt wird, während der andere Pol am Werkstück liegt, wobei jedoch das Lichtbogeriplasma nicht eingeengt ist.An arc welding torch is known from a publication, which has a long, has a relatively narrow channel with a constricting nozzle at the end that lies at one pole, and further comprising an electrode lying on the other pole and wherein gas along the electrode flows so that the arc both within the channel and subsequently and even more strongly in the Nozzle is narrowed, therefore it must be assumed that the arc has the known properties of the constricted arc, in particular an increased current density and an increased voltage drop each Unit of length. However, the document does not disclose that specifically in such Plasma jet a consumable electrode is to be used, but there is still a torch for Welding with a hollow electrode is described, through which a melting point at the arc Metal wire is fed, while the other pole is on the workpiece, but with the arc plasma is not constricted.
