Circular seam welding machine
Automated welding solutions for rotationally symmetrical workpieces

Automated and repeatable circular seams
Circular seam welding machines from Klumpp Welding are designed for precise joining of cylindrical components — depending on the application, as a structural, vertical variant in container construction or as a horizontally rotating version for pipe, chimney or pipeline structures. In both cases, circular seam welding machines precisely guide the welding head along the circumferential seam — for stable, repeatable connections in an automated process.
Details zu Rundnahtschweißmaschinen
Wann wird eine Rundnahtmaschine eingesetzt?
Bei der horizontalen Rundnaht wird das Werkstück entsprechend gelagert und gespannt, wodurch eine kontrollierte Schweißposition entsteht. Ein wesentlicher Vorteil liegt in der stabilen Führung des Schweißbades, da dieses nicht unkontrolliert verläuft.
Die vertikale Rundnahtschweißmaschine ermöglicht ebenfalls das Verschweißen von Umfangsnähten, unterscheidet sich jedoch in der Werkstückanordnung und Prozessführung.
Ihre Vorteile mit der Rundnahtschweißmaschine
Die richtige Spanntechnik für Ihre Anwendung
Ob Pneumatik oder Hydraulik eingesetzt wird, hängt insbesondere vom Werkstückgewicht und davon ab, wie gut das Bauteil vorgelagert gerundet wurde.
FAQs
Automation is possible. The workpieces are first clamped, then the machine can run a fixed welding program and can thus also be used for series parts. In addition, the positioning of flanges on the lateral surfaces can be integrated into the process. In addition, camera monitoring can be used to determine the shape and position of the parts or to check whether the correct parts have been clamped in. Seam tracking is also possible.
In principle, different materials can be processed. The material used depends on the selected welding process.
The possible material thicknesses are not generally limited by the type of machine construction. Material thicknesses of around 0.8-1.0 mm to 30 mm or 50 mm can be achieved.
There is no fundamental limit with regard to length or diameter. Workpieces of up to 12 meters in length have already been produced on a vertical circular seam welding machine and diameters of just under 8 meters on a horizontal circular seam welding machine.
All welding processes can be used.
With the vertical circular seam welding machine, welding is usually carried out from the outside. Internal welding is possible as long as the pipe is large enough. The horizontal circular seam welding machine with turntable is also mainly welded from outside. In individual cases, internal welding is also possible here, provided that there is enough space available for the welding head.
