A welding table is a high-precision work surface made of solid steel, designed as a stable foundation for professional metal construction and welding work. Compared to simple steel plates and improvised solutions, a Siegmund welding table is distinguished by three key features:

Precision perforated grid: A systematic hole pattern (system 16, 22 or 28) allows workpieces to be quickly fixed using clamping bolts, clamps, stops and squares.

Precise flatness: The milled surface ensures precise alignment of the components and prevents welding distortion and angular errors.

High surface hardness: Thanks to plasma nitriding and BAR coating, the tables are scratch-resistant, rust-protected and more resistant to the adhesion of weld spatter.

Conclusion: A welding table enables the efficient, safe, and precise fabrication of both simple and complex structures.

The characteristic hole grid is the core of a modern clamping system. Since metal expands when exposed to heat and contracts as it cools, the holes in the welding table are used to securely fix components in place and thereby prevent unwanted welding distortion.

Siegmund's hole grid solutions offer three key advantages for manufacturing on a welding/clamping table:

Modular clamping: Instead of time-consuming improvisation, you can use system components such as bolts, stops, and clamps. This allows you to create an accurate welding fixture in seconds, securely holding the material in place and at the correct angle.

3D flexibility: Special system squares allow the clamping surface to be easily extended vertically. This enables the precise tack welding and welding of complex, three-dimensional structures.

Maximum repeatability: Once defined, positions in the grid guarantee exact reproducibility of all components in series production.

Conclusion: The holes transform the welding table into an intelligent tool that significantly reduces setup times, minimizes errors, and ensures professional, dimensionally accurate results.

A professional welding table from Bernd Siegmund GmbH is a high-precision tool that far surpasses conventional steel plates in terms of stability and functionality. While improvised solutions often warp and become uneven under heat, the Siegmund system offers the following advantages:

Highest manufacturing precision: The precise hole pattern and flat surface allow workpieces to be fixed with millimeter accuracy. This eliminates welding distortion and saves time-consuming rework or complex straightening of the components.

Faster processes: Thanks to modular clamping elements, the need for cumbersome improvised fixings is eliminated. Complex constructions can be set up in record time.

Extreme durability: Thanks to plasma nitriding and BAR coating, weld spatter hardly adheres. The surface is extremely hard, scratch-resistant, and corrosion-resistant, whereas conventional structural steel wears and rusts quickly.

Maximum repeatability: The ergonomic design and grid system guarantee professional results with the highest dimensional accuracy – both for individual pieces and in series production.

Choosing the right hole system (16 mm, 22 mm, or 28 mm) depends largely on the weight of your components and the expected distortion forces. As a global market leader, Siegmund offers the right clamping system for every requirement.

System 16 (The precision system): Ideal for light to medium-duty work and precision fixtures. Thanks to the close 50 mm grid, small components can be fixed with high precision. Particularly suitable for finely dimensioned welded structures with minimal distortion.

System 22 (The all-rounder): The ideal middle ground in metal construction. It offers significantly greater stability than the 16 system, while remaining more manageable and cost-effective than the 28 system. Perfect for general metalwork and moderate distortion forces.

System 28 (The heavy-duty system): The global standard for heavy steel construction and mechanical engineering. With a 100 mm grid and heavy-duty bolts, it is designed for maximum clamping forces, multi-ton structures, and high distortion forces.

The ideal welding table size is determined using a simple rule of thumb: workpiece size plus an additional 200 to 300 mm of clearance on each side. This extra space is essential for stops, clamping elements, and clamps. Depending on the application, the following table sizes are recommended, for example:

Small parts: 1,0 m x 1,0 m or 1,2 m x 0,8 m (space-saving)

Standard metal construction (railings, frames): 2,0 m x 1,0 m or 2,4 m x 1,2 m

Large-scale projects & mechanical engineering: Sizes from 3,0 m x 1,5 m up to 4,0 m x 2,0 m

Thanks to the Siegmund modular system, the work surface can be flexibly expanded. Using U-Squares, aluminum profiles, or by connecting multiple tables with connecting bolts, you can create a continuous work surface of any size as needed.

The standard working height of a Siegmund welding table is typically between 850 mm and 950 mm. For ergonomic working, the rule of thumb is: for flat workpieces, the table surface should be approximately 10 to 15 cm below elbow height. For taller assemblies, a lower table is recommended, while a height of 700 mm to 750 mm is ideal for precision work and welding in a seated position.

Siegmund offers different leg systems for maximum flexibility:

Standard legs: With fine adjustment (approx. 50 mm) to compensate for uneven floors. Also available in height-adjustable versions.

Siegmund Smart Leg: Electrically height-adjustable for heavy loads (up to 4 t per leg) with 300 mm stroke and digital control.

Hydraulic lifting tables/lifting platforms: Allow for continuous adjustment to accommodate varying workpiece sizes.

The choice of material depends on the intensity of use and the workpiece. For maximum hardness, tool steel is the best choice. Here's an overview of the advantages and disadvantages:

Structural steel (S355J2+N) with plasma nitriding: The economical standard solution. It offers good protection against weld spatter and corrosion, but does not achieve the wear resistance of tool steel.

Through-hardened tool steel (Siegmund X8.7/ X8.8): The ultimate choice for professionals. Thanks to its extremely high base hardness and plasma nitriding, it is highly impact-resistant, scratch-resistant, and resistant to distortion.

Stainless Steel (V2A): The right choice exclusively for stainless steel manufacturing (e.g., in the food industry and medical technology). It prevents ferrite contamination (external rust). Because stainless steel is softer and more sensitive to heat, it is not suitable as an all-rounder for steelwork.

The price of a Siegmund welding table depends on the system size (System 16, 22, or 28) and the individual configuration. While the purchase price varies, a professional welding table typically pays for itself within 10 to 18 months in commercial use.

The investment in a premium system is worthwhile due to the following factors:

Up to 40% faster setup times*: Thanks to precise hole grid systems and standard clamping elements, you save significant working time on every project.

Lower operating costs: Thanks to plasma nitriding (surface hardening), weld spatter hardly adheres to the surface. This reduces the need for cleaning, abherents, and regrinding.

Long-term precision: Hardened tool steel with solid ribbing prevents warping – your table remains flat for years, unlike low-cost custom-built solutions.

Maximum flexibility: The modular system eliminates the need for costly custom fixtures for individual pieces.

Conclusion: A Siegmund welding table is not just a cost factor, but a productivity tool. The enormous time savings practically pay for the table itself. For a precisely calculated quote, we recommend consulting your local Siegmund dealer to configure the optimal setup for your components.

At Siegmund, professional grounding is achieved via a special ground connection that is fixed directly into the system bore. This ensures a 100% secure connection without overheating (up to 500 amps).

Touching the welding table during welding is permitted, provided safety regulations are observed, as only low welding voltage is present. Please note the following points:

Wear PPE: Never touch the table with bare skin; always use dry welding gloves and safety shoes for insulation.

Use caution in wet conditions: Moisture significantly increases the risk of electric shock.

Heat: Since steel tables retain process heat for a long time, there is a risk of burns.

The main difference lies in the vertical side panels: While a 2D welding table has a flat worktop with a hole grid, a 3D welding table additionally features four functional side panels with system bores. This allows for precise clamping beyond the table edge and the modular construction of complex fixtures in three-dimensional space.

The advantages of the 3D welding table at a glance:

Expandability: Stable connection of multiple tables or accessories via the side panels.

Precision: Right-angled setups can be fixed directly to the side of the table without the need for auxiliary constructions.

Stability: The side panels act as reinforcing ribs for maximum load capacity.

When is a 2D welding table sufficient?
A 2D welding table is the cost-effective professional solution for companies that primarily manufacture flat structures such as frames, gates or grilles and do not require vertical clamping options.

To maintain the precision and longevity of your Siegmund welding table, regular maintenance in three steps is recommended:

Protection (Prevention): Apply a high-quality anti-spatter spray before welding processes that produce a lot of spatter. This prevents weld spatter from sticking, so it can be easily wiped off after work.

Cleaning: Clean the surface regularly with a special cleaner (Siegmund CleanBasic) to completely remove grease and oils. Clean the system bores with a suitable brush. Important: Lightly oil the table after cleaning to ensure long-term corrosion protection.

Maintenance of uncoated tables: Use an oilstone to smooth out minor irregularities or weld spatter on an uncoated welding table. Important: For plasma-nitrided Siegmund welding tables, an oilstone is not necessary and may damage the surface hardening.
