Product Description

3D Welding Table 4000*2000mm Heavy Duty Portable Welding Work Station

This is a professional - grade large - scale welding workstation. It has dimensions of 4000mm (length) × 2000mm (width), belongs to industrial - grade heavy - duty welding equipment, and also features a portable design.

Specification

Basic parameters

Workbench size: 4000mm (length) × 2000mm (width) × (height adjustable, usually about 800 - 1000mm)

Tabletop thickness: usually 15 - 30mm (heavier models may be thicker) Material: Main body: Q355 high-strength steel (the surface can be galvanized or powder-coated for rust prevention)

Aperture: φ28mm (Internationally accepted standard, compatible with most fixtures)

Hole spacing: 100mm×100mm equidistant grid

Tabletop flatness ≤ 0.1mm/m² (High-precision processing to ensure the accuracy of welding positioning)

Application fields 

1.Large-scale metal structure manufacturing

2.Heavy machinery maintenance

3.Aerospace component welding

4.Automobile manufacturing and modification

5.Industrial equipment production

Accessories and Compatibility

Standard Accessories: Quick fixtures,, angle gauges, extension plates (to be purchased separately)

Compatible Fixtures: All standard fixtures with a diameter of φ28mm (such as clamps, , support columns)

Expansion Functions: Rotary modules, cantilever hanger brackets, or automated welding equipment can be installed

High precision welding worktable

Flexible Welding Platform  With Fixtures

Feature	Traditional Single-Sided Welding Table	5-Sided Welding Workstation
Working Surfaces	Top surface only	Top + 4 side surfaces for 3D operation
Clamping Efficiency	Requires frequent part flipping	Multi-surface simultaneous fixation, reduces hoisting
Complex Part Adaptability	Limited	Can position multiple irregular components simultaneously
Floor Space	Compact	Requires more space but increases efficiency by 300%

Main Features 

1.Extra-large working area:

The size of 4 meters by 2 meters provides a spacious working space.

is suitable for welding large workpieces or multiple projects simultaneously.

2.Heavy-duty load-bearing design:

Manufactured with high-strength steel.

The load-bearing capacity can reach several tons (please check the product specifications for the specific load-bearing capacity).

The stable structure can withstand heavy workpieces and powerful welding operations.

3.3D modular system:

The working surface is covered with positioning holes of standard size

(usually φ28mm or similar size).
The hole spacing is precisely consistent (commonly arranged at equal intervals of 50mm or 100mm).
It allows the positioning of workpieces and the installation of fixtures in three-dimensional space.
4.Portable design:
Despite its large size, mobility is considered in the design.
It may be equipped with heavy-duty casters or detachable parts for easy handling.
Some models may have a folding or modular design.

Technical Specifications

(Custom configurations available upon request.)

Aspect	Cast Iron	Q355 (Structural Steel)
