Abstract

Welding thin sheet metal as in BE 705081, Several non-fusible electrode are arranged in one row above the continuously moving sheet. The electrodes are fed from separate current sources and can be moved vertically and horizontally, either all together or singly. A coil, connected to a direct current source, is arranged around the electrodes to stabilise the electric arcs.

Die Erfindung sei anhand des in den Figuren 1 und 2 schematisch dargestellten Ausführungsbeispiels näher beschrieben. In an sich bekannte Weise wird ein Metallband zu einem Schutzrohr 2 geformt und der Schweifleinrichtung 3 zugeführt. Die Schweißeinrichtung 3 besteht im wesentlichen aus den drei hintereinander in Richtung des durchlaufenden Rohres 2 angeordneten Elektroden 4, die je einen gesonderten Lichtbogen führen. Zur Stabilisierung dieser Lichtbogen, das heißt, um Beinflussungen der Lichtbogen durch Felder auszugleichen oder zu verhindern, sind die drei Elektroden 4 von einer Spule 30 umgeben, die von einer Konstantstromquelle Jl gespeist ist. Das Magnetfeld der Spule 30 richtet die Lichtbögen der Elektroden k sozusagen aus, sodaß sie jetzt senkrecht zur Durchlaufachse des Rohres 2 und parallel zueinander stehen. Die Zahl der Amperewinduiigen der Spule 30 beträgt · etwa 600-750 AW und jede Elektrode führt eine Stromstärke von 2OO-25P Ampere.The invention will be described in more detail with reference to the exemplary embodiment shown schematically in FIGS. In a manner known per se, a metal strip is formed into a protective tube 2 and fed to the welding device 3. The welding device 3 consists essentially of the three electrodes 4 arranged one behind the other in the direction of the continuous pipe 2, each of which leads a separate arc. To stabilize these arcs, that is to say to compensate for or prevent influences on the arcs by fields, the three electrodes 4 are surrounded by a coil 30 which is fed by a constant current source J1. The magnetic field of the coil 30 aligns the arcs of the electrodes k, so to speak, so that they are now perpendicular to the axis of passage of the tube 2 and parallel to one another. The number of Amperewinduiigen the coil 30 is · about 600-750 AW and each electrode carries a current of 200-25P amps.
