Abstract
Description
Die Erfindung betrifft ein Verfahren und einen Schweißbrenner für das Metall-Schutzgasschweißen mit mechanischer Zuführung des drahtförmigen Zusatzwerkstoffes. Der Lichtbogen brennt zwischen der abschmelzenden Elektrode und dem Werkstück.The invention relates to a method and a welding torch for the Metal inert gas welding with mechanical feeding of the wire-shaped Additional material. The arc burns between the melting ones Electrode and the workpiece.
Das Metall-Schutzgasschweißen (MSG)
ist weit verbreitet. Beim Metall-Schutzgasschweißen gemäß der
Es ist üblich, das für das Metall-Schutzgasschweißen notwendige Schutzgas axial und konzentrisch um den Lichtbogen zuzuführen. Bekannt ist die gleichzeitige Zufuhr von 2 unterschiedlichen Schutzgasen mit unterschiedlichen Eigenschaften, mit dem Ziel der Verringerung des Anteiles des teureren Gases. Ebenfalls bekannt ist das Magnetisieren des Zusatzwerkstoffes zur Anhaftung magnetischen Pulvers, das so dem Schmelzbad zugeführt wird.It is common to do what is necessary for gas metal arc welding Shielding gas axially and concentrically to feed the arc. Known is the simultaneous supply of 2 different protective gases with different properties, with the aim of reducing the share of the more expensive gas. Magnetization is also known of the filler material for magnetic powder adhesion, so fed to the weld pool becomes.
Nachteilig bei Metallen mit niedriger Verdampfungstemperatur (zum Beispiel Magnesiumlegierungen) ist, dass aufsteigender Metalldampf vom Grundwerkstoff die Ablösung der flüssigen Metalltropfen von der abschmelzenden Elektrode behindert.Disadvantageous for metals with lower Evaporation temperature (for example magnesium alloys), that rising metal vapor from the base material detaches the liquid Metal drops blocked by the melting electrode.
Aus der
Es ist Aufgabe der Erfindung, den Lichtbogen so zu beeinflussen, dass die Energiedichte im Lichtbogen erhöht und die Tropfenablösung von der abschmelzenden Elektrode unterstützt wird.It is an object of the invention To influence the arc so that the energy density in the arc elevated and the drop detachment is supported by the melting electrode.
Erfindungsgemäß wird die Aufgabe durch ein Verfahren mit den im Anspruch 1 genannten Merkmalen gelöst. Vorteilhafte Varianten sind Gegenstand von Unteransprüchen.According to the invention, the object is achieved by a Method with the features mentioned in claim 1 solved. advantageous Variants are the subject of subclaims.
Weiterhin wird die Aufgabe durch einen Schweißbrenner mit den im Anspruch 6 genannten Merkmalen gelöst. Ausgestaltungen gehen aus den abhängigen Unteransprüchen hervor.The task continues through a welding torch solved with the features mentioned in claim 6. Refinements go out the dependent dependent claims out.
Der Schweißprozess läuft unter einem Schutzgas ab. Zusätzlich zum Schutzgas wird ein zweites Gas, das das gleiche sein kann wie das Schutzgas, zugeführt, dessen Strömung auf das abschmelzende Elektrodenende gerichtet ist und nachfolgend als Fokussiergas bezeichnet wird. Das Fokussiergas bewirkt eine Einschnürung des Lichtbogens und unterstützt die Ablösung der flüssigen Metalltropfen vom Zusatzwerkstoff Damit lassen sich höhere Schweißgeschwindigkeiten erreichen oder/und ein tieferer Einbrand im Grundwerkstoff erzielen.The welding process takes place under a protective gas. additionally the protective gas becomes a second gas, which can be the same as the protective gas, its flow is directed to the melting electrode end and subsequently is called focusing gas. The focusing gas causes one constriction of the arc and supports the detachment the liquid Drops of metal from the filler metal This enables higher welding speeds achieve or / and achieve a deeper penetration in the base material.
Mit dem Fokussiergas können auch pulverförmige Partikel (wie zum Beispiel Hartstoffe) gezielt dem Schmelzbad zugeführt werden, um die Eigenschaften des Schweißgutes zu beeinflussen.With the focusing gas, too powdery Particles (such as hard materials) are specifically fed into the weld pool, the properties of the weld metal to influence.
Die Erfindung wird nachfolgend an einem Ausführungsbeispiel noch näher erläutert. In den Zeichnungen zeigen:The invention will follow an embodiment even closer explained. The drawings show:
