What Size Welding Table Do I Need?

Choose a welding table size from the parts you fixture most often. If about 80% of your jobs fit a given footprint, start there. Then match the system to the work: Siegmund System 16 uses Ø16 mm bores on a 50 mm grid for light to medium-duty work and precision fixtures, while System 28 uses Ø28 mm bores on a 100 mm or diagonal grid for light to heavy components and high clamping forces. Siegmund states load per leg: System 16 1,000 kg, System 28 2,000 kg and System 28 PLUS 3,000 kg. Exclusive Canadian importer of Siegmund. Ships across Canada from St. Marys, ON; most orders ship within 48 hours.

Before you pick a size, answer three questions: how big are the parts you fixture, how thick is the material, and how heavy is the finished project?

Start with part size: the 80/20 rule

Few shops know every job that will come through the door. A simple 80/20 rule narrows the choice: if 80% of your parts fit a table size, that size is likely the best option. You can join Siegmund tables with connecting bolts or add squares and U-shapes to widen or lengthen the work area when a bigger job arrives. Expansion is built into the system.

Material thickness and holding force: System 16 or System 28

Siegmund defines each system by its bore size, and says the choice depends on the type and size of the workpieces and the distortion forces you expect.

• System 16 — Ø16 mm bores on a 50 x 50 mm grid. Siegmund describes it as ideal for light to medium-duty work and precision fixtures; the close grid lets you fix small components precisely. See System 16 welding tables.
• System 28 — Ø28 mm bores on a 100 x 100 mm or diagonal grid. Siegmund describes System 28 as ideal for light to heavy components and designed for maximum clamping forces, multi-ton structures and high distortion forces. See System 28 welding tables.

All tooling within one system fits every table series in that system. System 16 tooling also fits other 16 mm tables with Ø16 mm bores on a 50 mm grid, and System 28 tooling fits other 28 mm system tables with Ø28 mm bores on a 100 mm grid.

Load capacity is stated per leg

Siegmund gives load per leg with basic equipment, and notes that the usable load depends on the type and number of legs:

• System 16: max. 1,000 kg (2,205 lb) per leg
• System 28: max. 2,000 kg (4,409 lb) per leg
• System 28 PLUS: max. 3,000 kg (6,614 lb) per leg

If you plan to put the table on casters, ask us for the rating of the caster option on your model before you order.

Need adjustable height?

If several people share the table or the work changes height often, look at the PETec table lift systems.

Smaller shop? Consider a System 16 workbench

Siegmund System 16 workbenches use the same Ø16 mm bore and 50 mm grid in 1200 x 800, 1500 x 1000 and 2000 x 1000 mm sizes.
