Description

Einrichtung zum Verschweißen von Drähten aus Metallen verschiedener Schweißeigenschaften Während sich die Enden von Drähten aus dem gleichen Metall meist ohne Schwierigkeiten miteinander verschweißen lassen, treten bei der Verschweißwng von Metallen verschiedener Schweißeigenschaften Schwierigkeiten auf. Um diese Schwierigkeiten zu beheben, hat man besondere Schweißeinrichtungen vorgesehen. Eine bekannte derartige Schweißeinrichtung hat zwei an einer Sch@vetiß,stromquelle angeschlossene und in Richtung der Längsachse der miteinander zu verschweißenden Drahtenden bewegliche Spannböcke, die mit einem die Stoßenden der Drähte unter Bildung eines Lichtbogens kurzzeitig trennenden und dann ineinanderstauchende.n Antrieb gekuppelt sind. Die Erfindung macht von dieser Einrichtung Gebrauch. Um besonders feste Schweißverbindungen gleichbleibender Güte, namentlich beim Verschweißen von Kupfer- und Alum@i.niumdrähten, zu erhalten, ist erfindungsgemäß der Spannbock für den Draht mit .der kleineren Leitfähigkeit bzw. das bei der Erhitzung rascher schmelzen & Drahtende mit einer die Schweißstelle aufnehmenden, vorzugsweise kelch- oder glockenförmigen Aussparungen versehen.Device for welding wires made of different metals Welding properties While the ends of wires are made of the same metal can usually be welded to one another without difficulty, occur during the welding of metals with different welding properties have difficulties. To these difficulties to remedy, one has provided special welding equipment. A well-known one Welding device has two connected to a Sch @ vetiß, power source and in Movable direction of the longitudinal axis of the wire ends to be welded together Clamping stands that join the butt ends of the wires to form an arc Briefly separating and then interlocking drives are coupled. the Invention makes use of this facility. About particularly strong welded joints consistent quality, especially when welding copper and aluminum wires, to obtain, according to the invention, the clamp for the wire with .der smaller Conductivity or that melt faster when heated & wire end with a Preferably cup-shaped or bell-shaped recesses that accommodate the welding point Mistake.

Diese Aussparung bietet den Vorteil, daß sie den Lichtbogen vor der Einwirkung magnetischer ßlasfelder oder Luftströme schützt, die eine Ablenkun- des Lichtbogens 'herbeiführen könnte, und so gewissermaßen für die Konzentrierung des Lichtbogens auf die Schweißstelle .sorgt. Damit ist eine Verringerung des Ausschusses beim Schweißen gewährleistet.This recess has the advantage that it starts the arc in front of the The effects of magnetic glass fields or air currents, which are a distraction Arc ', and so to a certain extent for the concentration of the Arc on the welding point. This reduces the number of rejects when welding guaranteed.
