Longitudinal seam welding machine
For linear seam connections in automated manufacturing processes
Reproducible, stable and in line with requirements
Longitudinal seam welding machines from Klumpp Welding are used to produce straight welds along the longitudinal axis of sheets or rotationally symmetrical components. The machines precisely guide the welding head and enable stable, repeatable processes.
Suitable clamping and positioning devices are available for different requirements, which securely fix the component and align it to the defined seam length. The welding machine and process are selected on a customer-specific basis.
Longitudinal seam technology forms the basis for various types of machines. The longitudinal seam is often used as part of a multi-stage manufacturing process, for example in container construction in combination with circular seam processes.
We flexibly adapt our basic models of longitudinal seam welding machines to individual customer requirements. We have virtually no limits when it comes to the length, height and width of the workpieces.
The mandrel is optionally available in a rotatable version. In this way, several rails can be opened at the same time and used one after the other by simply turning them on, so that different materials can be welded without complex retooling. In addition, the front clamping area can be designed as a separate mechanism to clamp independently of the main clamping system.

Details zu Längsnahtschweißmaschinen
Wann wird eine Längsnahtschweißmaschine eingesetzt?
Der Schweißkopf wird – unabhängig vom gewählten Schweißverfahren – präzise entlang der zuvor eingespannten Blechkanten geführt und verbindet die Bauteile automatisiert miteinander. Die Nahtvorbereitung erfolgt in der Regel vorgelagert, während nachgelagerte Bearbeitungsschritte wie das Verschleifen oder Drücken der Naht separat durchgeführt werden. Klumpp Welding bietet hierfür Längsnahtschweißmaschinen in kundenspezifischer Ausführung an.

Die richtige Spanntechnik für Ihre Anwendung
Bei größeren Materialdicken oder höherem Verzug wird in der Regel hydraulisch oder hochdruckhydraulisch gespannt, um eine stabile und kraftschlüssige Fixierung sicherzustellen.
Entscheidend ist dabei auch die Qualität des vorgelagerten Rundungsprozesses: Je präziser das Bauteil vorgeformt ist, desto geringer ist die erforderliche Spannkraft. In solchen Fällen kann auch bei höheren Materialstärken eine pneumatische Lösung ausreichend sein.

FAQs
The length of the workpiece can be implemented flexibly. Systems that have already been implemented allow welding lengths of up to 16 meters.
Components with diameters of up to 20 meters have already been manufactured. The design is project-specific.
Automation is possible. For example, automatic unloading of the machine can be integrated. With the roof training machine, it is also possible to automatically bend the parts on the machine. In addition, Klumpp Welding can also integrate the supply technology for the components and the positioning of the parts to be welded into the process.
All common welding processes can be integrated. The selection is customer-specific and depends on material, seam requirements and quality standards.
The mandrel can move linearly or be tilted using hydraulic or compressed air cylinders. As a result, the machine can be adapted to different workpiece diameters and installation situations.
In principle, all materials suitable for welding can be processed. The welding process used and the seam quality depend on the selected welding machine and the respective process requirements.
Depending on the application, material thicknesses of around 0.3 mm to 30 mm can be achieved. The exact design depends on the material and welding process.
Welding is possible both on the inside and on the outside of the container. The design depends on component size, accessibility and quality requirements.
