A longitudinal seam clamping device is what makes precise welding possible in the first place. It fixes the joining zone of the workpiece along the longitudinal seam and delivers impressive, reproducible quality - from thin sheets and plates to solid pipes. In combination with the modular design from Schnelldorfer Maschinenbau, this creates a system that guarantees process stability, productivity and seam reliability over the entire length. For the best welding results.
Why the clamping device makes the difference
A high-quality clamping device is the basis for a precise and clean welding result. It fixes the workpiece in the correct position so that the weld seam is created exactly where it is supposed to be - without slipping or distortion. At the same time, it compensates for the thermal stresses that arise during welding and keeps the joining zone stable across the entire sheet thickness. This keeps the seam shape constant, the heat input controllable and reworking minimal. In short: a good clamping device creates a convincing welding quality and also saves time and costs in production.
Benefits of a longitudinal seam tensioning device at a glance
- Dimensionally accurate weld seam over the entire length
- Reliable clamping for any sheet thickness
- Shorter set-up times for the operator
- High quality thanks to sturdy steel construction and machine body
- Flexible with MIG/MAG and laser
Fields of application: Sheet metal, plates and pipes
The longitudinal seam clamping device shows its strengths wherever sheet metal, plates or pipes need to be joined permanently and precisely, for example in apparatus engineering, tank construction or automotive engineering. It covers a wide range of materials, from stainless steel and aluminum to copper and classic structural steels. Fine visible seams can be produced just as reliably as load-bearing structural seams, which impress with their high strength and tightness. Thanks to the precisely defined clamping length, the joining process remains under control throughout, and even large panels and long pipes can be joined with uniform heat input. The result is homogeneous, tight and visually clean longitudinal seams that impress with every detail.
Longitudinal seam clamping bench and steel construction
The longitudinal seam clamping bench delivers what it promises: absolute stability and precise welded joints. Its robust steel construction retains its shape even with large components and noticeably reduces vibrations. The machine body remains steady and torsion-free during the entire welding process - a clear advantage for even seams and precise results.
All components work together and under the best conditions, which extends the service life of the system and keeps quality consistently high, even in multi-shift operation. The low-maintenance design reduces maintenance costs and makes the longitudinal seam clamping bench a reliable partner in any production environment.
Clamping to perfection: clamping length, height and turnbuckle
Perfect clamping is achieved through precision and control. Clamping bars, stable stops and finely adjustable supports hold the workpiece securely in position over the entire clamping length. Particularly ingenious: The adjustable height compensates for tolerances between sheets, plates or pipes. A turnbuckle also provides additional support, with positive locking, repeat accuracy and stability, even with changing geometries. Meanwhile, the joining zone remains stable and the weld seam is uniform in depth and shape.
For the operator, this means a clear view of the longitudinal seam and safe, ergonomic working: The operator can see what he is doing and can follow every setting exactly. For precise welding in every production situation.
Impressive ergonomics and suitability for everyday use
A longitudinal seam clamping device only shows its quality when it is easy and safe to operate in everyday use. Clear scales for height and clamping length, defined positions and free access to the joining zone - all this makes work clear and precise. Integrated lighting, well-placed viewing windows and quick-change supports provide extra ergonomics and suitability for everyday use. This saves time and relieves stress, especially on long working days.
Welding processes: MIG, MAG, TIG/TIG and plasma
The longitudinal seam clamping device from Schnelldorfer Maschinenbau is designed for all common welding processes: MIG, MAG, TIG/TIG and plasma. It can be used to join sheet metal, plates, pipes and housings made of stainless steel as well as steel and aluminum easily and precisely.
- MIG/MAG welding impresses with its high deposition rate and fast speed. The process works reliably and efficiently even with thicker material.
- The laser welding process, on the other hand, enables extremely precise, clean and virtually spatter-free weld seams that are characterized by high strength and excellent optical quality - ideal for thin materials, complex component geometries and demanding surfaces.
With all welding processes, it is possible to achieve reproducible results from tacking to the final run thanks to the precisely defined torch distances, controlled feed speed and seam-accurate guidance. For the best possible seam quality in every application.
Control, functions and intelligent options
The control system of the longitudinal seam welding machine is modern, clear and intuitive. Everything can be conveniently set via a clearly structured interface - contact pressure, travel speed, torch position and even the working height. This saves time and creates a consistently good welding pattern. Practical additional functions such as the automatic start/stop sequences and predefined seam recipes, forming gas management and data logging make the process even more efficient and reliable. This keeps the focus on welding, not on setting.
Another plus point: thanks to the open system architecture, the system can be expanded at any time. Sensors, seam tracking or documentation modules can be easily integrated at any time. In this way, the longitudinal seam tensioning device grows with the requirements - whether in series production or for special projects.
Quality of the weld seam - copper overlay and controlled heat balance
Every weld seam should be perfect - and to achieve this, the right heat distribution is essential. Copper supports stabilize the arc, reliably dissipate excess heat and thus protect sensitive edges from overheating. Cooling channels integrated into the steel construction also keep the temperature constant along the entire longitudinal seam, preventing overheating. Both of these features pave the way for uniform penetration, smooth weld seams and consistently high quality that is both visible and measurable. Even with long lengths or thick sheet thicknesses, the seam remains free of deformation and visually flawless.
Your options - different variants and sizes
From the compact table system for small sheets to the large longitudinal seam clamping bench for long tubes - each version can be precisely adapted to the workpiece size used and the desired sheet thickness and seam length. Practical quick-change turnbuckles, modular supports and convenient additional options such as forming chambers, automatic torch tracking or special supports also significantly extend the range of applications. Whichever version you choose, one thing is certain: you always have the option of configuring your longitudinal seam welding machine individually, as this is an integral part of the concept. For performance and results that are spot on.
