Longitudinal seam welding systems

Automated longitudinal seam welding system from Fronius.

Longitudinal seam welding: which systems and materials are most suitable?

High seam quality, process reliability, and flexibility are crucial when welding longitudinal seams in tank and plant construction.

The longitudinal seam welding systems from Fronius are designed as seam welders for internal and external welding. Suitable for both single batch and series production, they enable the reproducible production of weld seams for specific metalworking requirements. Thanks to a range of welding processes and flexible equipment options, these welding systems can be optimally adapted to different component geometries and production conditions.

Each application has its own particular requirements with regards to material, wall thickness, and seam quality. For longitudinal seam welding, the process can be precisely adapted to suit a variety of materials and their specific areas of application.

Fronius modular clamping bench iSeamer
iSeamer
The iSeamer is a modular seam welder that combines solid mechanical engineering with powerful system controls. It is capable of processing cylindrical and conical components using configurable variants and conventional welding processes. This allows dependable, high quality welding of pipes with diameters of 80 to 1250 mm and straight sheets with component lengths of up to 4100 mm.
