Description

, Beim Schweißen mit dem elektrischen Lichtbogen kann man wegen der geringen räumlichen Ausdehnung der Wärmequelle stets nur kleine Schweißnähte ausfüllen. Bei weiteren Schweißnähten ist man gezwungen, die Naht zunächst in der üblichen Weise auszuschweißen und dann je nach Bedarf noch ein oder mehrere Male zu überschweißen. Die Erfindung bezieht sich auf eine Einrichtung, durch dieWhen welding with the electric arc one can because of the small spatial Expansion of the heat source always fill in only small weld seams. With further Welding seams you are forced to first weld the seam in the usual way and then weld over one or more times as required. The invention refers to a facility through which

ίο dieser Prozeß des Überschweißens vereinfacht wird.ίο this process of over-welding is simplified will.

Nach der Erfindung erhält ein Lichtbogen-Schweißapparat zum Schweißen langer Nähte Elektroden für mehrere Lichtbogen in solcher Anordnung, daß bei Fortbewegung des Apparates längs der Schweißnaht der eine Lichtbogen die vom andern geschweißte Naht nochmals überschweißt. Im allgemeinen wird man mit zwei Lichtbogen auskommen, doch ist es ohne weiteres möglich, auch drei oder mehr Lichtbogen räumlich hintereinanderzuschalten.According to the invention, an arc welding apparatus for welding long seams is obtained Electrodes for multiple arcs in such an arrangement that when the apparatus is moved along the weld seam of one arc, the seam welded by the other again welded over. Two arcs will generally be sufficient, but it is It is easily possible to also connect three or more arcs spatially one behind the other.

Der Schweißapparat selber kann dabei als Handschweißapparat oder auch als automatischer Schweißapparat ausgebildet sein. Die Zuführung des Schweißgutes zum Lichtbogen oder der Nachschub des Elektrode nmaterials bei Schweißapparaten, bei denen die Elektrode selber das Schweißgut liefert, kann dabei durch gemeinsam angetriebene Nachschubvorrichtungen bewerkstelligt werden.The welding machine itself can be used as a manual welding machine or as an automatic one Be formed welding machine. The feeding of the weld metal to the arc or the replenishment of the electrode material in welding machines that use the electrode supplies the weld metal itself, can by means of jointly driven feed devices be accomplished.
