Product Overview
Tired of easily‑scratched worktops, sticky welding spatter and frequent coating peeling on ordinary welding tables?
Our Nitrided Surface Welding Table applies professional plasma nitriding heat‑treatment on fully‑machined five‑sided working surface. Hardened surface greatly reduces spatter sticking and simplifies daily cleaning. High‑precision hole‑system ensures repeat positioning accuracy. Choose Q355 steel or HT300 cast iron base material, D16 / D28 hole patterns and custom sizes up to 4800×2400 mm to match your welding‑work cell requirements. Contact us to get your technical solution and quotation.

Core advantages

High Purity Q355 steel Material
Tougher and more resistant to use

In-stock goods
Source manufacturer with guaranteed production capacity

High precision fixtures
Made by CNC machine,16mm/28mm two systems are compatible.

Adjustable legs
4 types legs:standard legs/adjustable legs/caster wheel legs/square legs
Anti welding slag splashing, easy to clean
After nitriding, the surface energy decreases, and welding spatter and slag are less likely to melt and stick to the table surface. They can be cleaned with a copper brush/nylon brush without the need for vigorous polishing; Significantly reduce the damage caused by polishing to the reference plane.
high wear resistance and scratch resistance
Dragging heavy objects and repeatedly bumping fixtures make it difficult to press out dents and scratches, greatly improving the service life of the workbench reference plane; Suitable for high-intensity daily production of Siegmund W... in factories.
Rust and corrosion resistance (surface layer)
The dense nitride layer resists workshop moisture, cutting fluid, and slight corrosion; Note that it is not permanently completely rust proof. If the nitrogen layer is scraped through, the exposed substrate will still rust and requires daily maintenance.
No coating peeling problem
The paint on the spray painted surface quickly rusts after being knocked off; Nitriding is a matrix modification that does not cause peeling or detachment, and has good long-term appearance consistency.
Good precision retention
Nitriding low-temperature treatment does not damage the flatness and hole accuracy of machining, and the fixture repeatability positioning accuracy is stable. The Nitrided Surface Welding Table is suitable for batch welding production and robot welding workstations.
splicing function

The welding table is equipped with splicing pin holes on the side; By using positioning pins and locking bolts, multiple units can be seamlessly assembled into a super large workbench (such as 2000 × 4000mm).
After splicing, the seam misalignment should be ≤ 0.05mm; the splicing pin must be matched with the hole system D16/D28.
Attention: After splicing, the entire workbench must be placed on a rigid support as a whole. It is not allowed to place separate supports on each table separately, otherwise the splicing seam will be staggered.

Real performance of thermal deformation
Welding slag splashing: can reduce welding slag adhesion and make cleaning easier, but it is not completely free of welding slag adhesion; High current MIG welding, with high splashing energy, will still stick slag, requiring copper brush cleaning.
Local high temperature: When the workpiece is directly welded with high heat on the table, the table will still experience slight thermal expansion due to local heating; The temperature will recover when it drops.
Electric arc burning: The electric arc directly strikes the tabletop, with a local temperature of thousands of degrees, which will burn through the nitriding layer and form pits. This damage cannot be avoided by the nitriding process.
