Description

  

  Verfahren zum Lichtbogenschweissen mittels ummantelten Elektroden.         Gegenstand    des     Patentanspruches    I des  Hauptpatentes ist ein Verfahren zum Licht  bogenschweissen mittels ummantelten, auf  die Schweissstelle aufgelegten Elektroden,  bei     welchem    der Lichtbogen und zumindest  der abbrennende Teil der Elektrode von  einem Körper überdeckt werden, der der  Form der Elektrode so     weit    angepasst     isst,    dass  er sie in ihrer Lage längs der Schweissstelle  festhält und der auf beiden Seiten der Elek  trode mit dem Werkstück in Berührung  steht.  



  Gemäss der Erfindung kann nach diesem  Verfahren auch mit     Drehstrom    geschweisst  werden, indem unter den Abdeckkörper meh  rere mit zwei verschiedenen Phasen eines  Dreiphasensystems verbundene, ummantelte  Elektroden angeordnet werden und .die     dritte     Phase mit. dem     Werkstück    verbunden wird.  Es hat sich gezeigt, dass auf .diese Weise  gute Schweissnähte erzielt werden können,  wobei das Dreiphasensystem zumindest an  nähernd gleichmässig     belastet    ist. Zur Durch-    Führung solcher Schweissungen können an  sich     bekannte,    vorzugsweise regelbare  Schweisstransformatoren oder Vorschaltimpe  danzen verwendet werden.

   An Stelle eines  Mehrphasentransformators. kann auch eine  entsprechende Zahl von Einphasentransfor  matoren verwendet werden.  



  Im folgenden werden an Hand der Zeich  nung einige Ausführungsbeispiele des Ver  fahrens erläutert. In den Fig. 1 bis 3 sind  die zu verbindenden Werktücke mit 1 und 2,  der Abdeckkörper mit 3, und die Elektroden  mit 4 bezw. 5 bezeichnet. Während bei .der  Anordnung nach Fig. 1 die Elektroden den  üblichen kreisförmigen     Querschnitt        besitzen,     zeigt Fig. 2 die, Verwendung von ummantel  ten Elektroden mit eckigem Querschnitt, die  gut in die Schweissfuge passen. Nach     Fig.    3  werden die beiden Elektroden     übereinander     angeordnet.

   Die     Fig.    4, 5 und 6 zeigen um  mantelte Doppelelektroden, die an     die,Stelle     der     beideneinzelnen    gemäss den vorhergehen  den Figuren verwendeten Elektroden treten      können. Die Fig. 7 und 8 zeigen die Anwen  dung des Verfahrens zur Auftragsschwei  ssung mittels Drehstrom. Die Phase R liegt  am     Werkstück,    die Phasen     S    und T sind  nach Fig. 7 mit der ersten bezw. zweiten  Hälfte der Elektroden, nach Fig. 8 mit den  Elektroden ungeradzahliger bezw. geradzahli  ger Ordnungszahl verbunden. Für diesen  und andere Zwecke können Doppelelektroden  oder auch Mehrfachelektroden mit mehr als  zwei innerhalb einer gemeinsamen Um  mantelung liegenden Schweissstäben verwen  det werden. .



  Arc welding process using coated electrodes. The subject of claim I of the main patent is a method for arc welding by means of coated electrodes placed on the welding point, in which the arc and at least the burning part of the electrode are covered by a body that is adapted to the shape of the electrode so that it eats holds them in their position along the weld and the electrode is in contact with the workpiece on both sides of the elec- trode.



  According to the invention, this method can also be used to weld with three-phase current by placing several encased electrodes connected to two different phases of a three-phase system under the cover body, and with the third phase. is connected to the workpiece. It has been shown that good weld seams can be achieved in this way, with the three-phase system being at least approximately evenly loaded. To carry out such welds, known, preferably controllable welding transformers or ballast impedances can be used.

   Instead of a multi-phase transformer. A corresponding number of single-phase transformers can also be used.



  In the following some exemplary embodiments of the process are explained with reference to the drawing. In Figs. 1 to 3, the workpieces to be connected with 1 and 2, the cover with 3, and the electrodes with 4 respectively. 5 designated. While in the arrangement of FIG. 1 the electrodes have the usual circular cross-section, FIG. 2 shows the use of encased electrodes with an angular cross-section that fit well into the weld joint. According to FIG. 3, the two electrodes are arranged one above the other.

   4, 5 and 6 show coated double electrodes which can take the place of the two individual electrodes used according to the preceding figures. 7 and 8 show the application of the method for build-up welding by means of three-phase current. The phase R is on the workpiece, the phases S and T are shown in FIG. 7 with the first respectively. second half of the electrodes, according to FIG. 8 with the electrodes of odd numbers respectively. even ordinal number connected. For this and other purposes, double electrodes or multiple electrodes with more than two welding rods lying within a common sheath can be used. .
