The quality of a welded joint is often associated with factors such as the welding process, filler material, or the welder’s qualifications. However, one key influencing factor is frequently underestimated: clamping technology. Even before welding begins, the precise positioning and secure fixation of components play a decisive role in dimensional accuracy, repeatability, and ultimately the quality of the entire manufacturing process.
Siegmund therefore regards clamping technology not merely as a supporting tool, but as an integral part of welding quality assurance. With its modular welding table systems and comprehensive range of modular components, the company offers solutions that enable maximum precision in both one-off production and automated series manufacturing.
Today, a modern welding table serves far more than simply as a stable work surface. It provides a highly precise reference plane for all clamping, positioning, and measuring tasks throughout the manufacturing process.
Welding tables from Bernd Siegmund GmbH are characterized by high levels of flatness and dimensional accuracy, providing the foundation for precise and repeatable workpiece positioning. The accurately manufactured hole grid forms the basis for reproducible setups and allows fixtures to be recreated identically at any time. This makes it possible to manufacture both individual parts and recurring assemblies with consistently high quality.
Especially when working with complex welded structures, this level of precision helps eliminate potential sources of error at an early stage and sustainably reduces rework and scrap.
Depending on the workpiece, requirements regarding clamping technology and load capacity can vary considerably. Siegmund therefore offers its welding tables in three proven system sizes: 16, 22, and 28.
The classic System 28 provides a versatile solution for general metal fabrication and offers high clamping and holding forces for large workpieces. System 22 bridges the gap between general mechanical engineering and more delicate applications, while System 16 is designed for smaller components and intricate structures.
This graduated system architecture allows users to tailor their clamping equipment precisely to their manufacturing requirements without compromising on precision or cost-effectiveness.
One of the key advantages of the Siegmund system is its modular design. Whether System 28, 22, or 16, all clamping components are based on a standardized hole grid and can be intuitively combined.
Squares, stops, bolts, eccentric stops, clamps, spacers, and numerous other components make it possible to quickly create customized clamping fixtures. Even complex positioning tasks can be accomplished without the need for elaborate custom-made fixtures.
The standardized system offers several key advantages:
Particularly in one-off and small-batch production, this modular approach can result in significant time and cost savings.
During welding, considerable thermal forces act on the workpiece. Without secure fixation, even minor movements can lead to dimensional deviations and affect the quality of the weld.
The clamping components from Bernd Siegmund GmbH ensure that workpieces are held securely in place. Their ergonomic design enables easy operation and supports comfortable and efficient working. Thanks to flexible adjustment options, different variants within a component or assembly family can also be quickly reconfigured and manufactured efficiently.
For demanding applications, special clamping components are also available that allow workpieces to be selectively preloaded. This controlled preloading can be used to compensate for anticipated deformation caused by heat input. The result is improved dimensional accuracy and a significant reduction in rework and straightening.
In addition to geometric precision, the quality of the table surface plays a decisive role in ensuring the long-term performance of a welding table.
A key feature of many Siegmund welding tables is their plasma-nitrided surface. Bernd Siegmund GmbH was one of the first manufacturers to use this proven technology as a standard feature on welding tables, thereby establishing a new industry standard. The treatment creates an exceptionally hard and wear-resistant surface without compromising the table’s high level of flatness and dimensional accuracy.
The benefits of plasma nitriding include:
In everyday workshop environments in particular, the reduced adhesion of welding spatter makes cleaning considerably easier and helps maintain the precision of the system over the long term.
For Bernd Siegmund GmbH, quality does not end with product design. All components are subject to internally defined quality standards that are continuously developed and improved.
Regular product inspections, comprehensive measurement procedures, and continuous optimization of manufacturing processes ensure that precision, load capacity, and functionality are consistently maintained at the highest level. This systematic approach to quality assurance is a key factor in achieving high customer satisfaction and maintaining the company’s strong position in international markets.
Even before a clamping fixture is physically assembled, the Siegmund Configurator supports users in project planning. Clamping and welding setups can be digitally visualized, planned, and documented.
This allows clamping concepts to be optimized during the planning phase, potential collisions to be identified at an early stage, and workflows to be prepared efficiently. At the same time, digital documentation simplifies the repetition of identical manufacturing tasks and supports standardized production processes.
In addition to its extensive standard product range, Bernd Siegmund GmbH develops customized solutions tailored precisely to specific customer requirements. Through close collaboration with customers, individual clamping solutions can be created and seamlessly integrated into existing manufacturing processes.
Particularly for large welded assemblies, special-purpose machinery, or automated production lines, this approach enables cost-effective solutions that integrate efficiently into existing production workflows.
Reproducible welding quality begins long before the actual welding process. Precise clamping technology creates the conditions required for dimensionally accurate components, stable manufacturing processes, and cost-effective production.
With high-precision welding table systems, a modular range of clamping components, innovative surface treatments such as plasma nitriding, digital planning tools, and customized solutions, Bernd Siegmund GmbH provides a comprehensive system that treats clamping technology as an integral part of welding quality assurance. For users, this means not only greater process reliability, but also increased efficiency, shorter setup times, and consistently high manufacturing quality.
