Longitudinal seam welding machine

The longitudinal seam welding machine is intended for classic applications and is limited to its core functions. It has various locking pins and is operated in such a way that the workpiece — such as a container — is positioned below the machine.

This machine has an integrated lift table to position the component. The workpiece can thus be raised, lowered and moved out of the system. Thanks to its raised design, the machine also allows larger containers to be placed in the lower working area.

This version is equipped with a mechanical press and is usually combined with a lift table. The presser is used to securely position the component before the welding process, especially in the case of thicker sheets.

The roof training machine is designed as an integrated solution for manufacturing container lids. An inserted round plate is first clamped on one side and then pulled into shape with a presser — directly on the same machine. The combination of forming and longitudinal seam welding in one operation makes it a 2-in-1 solution developed exclusively by Klumpp Welding. In principle, this design can also be used to weld containers above the machine

These machines are designed for applications where the container is positioned and assembled above the machine. In contrast to the standard version, in which the workpiece is guided underneath, the longitudinal seam welding is carried out from above.

This machine can be swivelled 90 degrees. The container is first oriented in an upright position and then brought into a welding position. The advantage: The weld pool remains stable and controllable — ideal for process-reliable longitudinal seams.

This system combines longitudinal and circular weld welding in one system. A central cantilever moves the components between the stations so that both seam shapes can be processed in one go — for greater efficiency in the manufacturing process.
