How to choose a welding table: the complete buying guide

The system refers to the diameter of the clamping holes in the top plate. Ø28mm is the most used system in metal and steel fabrication: the 28 mm holes and coarse grid carry heavy workpieces and large clamping forces. The Ø16mm system has a finer grid of 50 × 50 mm and is meant for smaller parts, jigs and precision work where you clamp more often and closer together.

Not sure? For most workshops Ø28mm is the safe choice. If you mainly work with small, fine parts or build jigs, Ø16mm is more precise. Both systems are available at DCT, including matching clamps, squares and stops.

Measure your largest common workpiece and add room on every side for clamps, stops and squares. A table that fits exactly leaves no room to clamp properly. Also consider working height: an ergonomic height prevents back strain during long welding, and with adjustable legs or a scissor lift you match the height to the job.

Occasionally have a larger workpiece? You extend the work surface with U-beams and clamping angles, or couple two tables together. That way you don't have to buy the largest table straight away.

DCT welding tables are CNC-milled from solid S690QL, a high-quality, fine-grained steel with a high yield strength. They are then gas-nitrided to a surface hardness of around 800 HV.

Gas nitriding is not a coating. During nitriding, nitrogen diffuses deep into the steel and hardens it from the inside out. The result does not wear away like paint or powder coating, transfers nothing onto your workpiece, and makes weld spatter stick less and come off more easily. That extends the lifespan and keeps the top plate flat and reliable for years.

Why does this matter for your choice? A soft or untreated top plate picks up pits and damage from grinding discs and spatter faster, and loses its flatness as a result.

A welding table is your reference surface: everything you clamp on it takes on the flatness of the table. If the plate is warped or damaged, you build that deviation into your workpiece. That's why a flat, hardened top plate and accurately drilled, square clamping holes matter more than any brand logo.

When comparing, look at the stated flatness tolerance and the squareness of the holes. Together those two determine how clean your 90° joints and corner setups turn out.

The Ø28mm grid is a de facto standard. So you're not tied to one brand: existing clamps, bolts and stops from Siegmund or Demmeler stay usable, and you reorder more cheaply without rebuilding your whole workshop. That way you avoid brand lock-in and keep your investment flexible.

Already have a table or tools from another brand? Check whether it's the Ø28mm (or Ø16mm) system, then it's combinable.

Prices for technically comparable tables vary a lot between brands. DCT delivers A-brand quality, with the same Ø28mm system and the same nitrided steel, up to 40% cheaper than the best-known brands, because we deliver directly from our own stock.

So compare on specification: steel grade, surface hardness, flatness and compatibility. Also factor in what separate accessories cost and how fast you can get delivery. At DCT many products are in stock, with fast delivery across Europe.
