Flexible Positioning 3D Welding Table for Complex Components
Flexible Positioning 3D Welding Table for Complex Components is a modular high-precision tooling system specifically designed for complex components. Its core feature is the use of standardized hole systems combined with quick-lock modules to achieve rapid three-dimensional positioning in X/Y/Z directions. It is suitable for various small-batch and complex welding scenarios with significantly higher efficiency and accuracy compared to traditional rigid tooling:
- Tabletop Hole Pattern: 16mm diameter + 50mm equidistant grid, tabletop thickness ≥80mm (to ensure load-bearing capacity and precision)
- Surface Treatment: Nitriding treatment (hardness HV800+), resistant to welding slag abrasion and corrosion
- Clamping Kit: Includes adjustable positioning blocks, angle positioning rulers, curved supports, quick clamps, multi-size pressure plates, etc. (usually ≥80 pieces)
- Support System: Optional adjustable support feet (for leveling the tabletop), magnetic base holders (for auxiliary positioning)
Key core features
-
Three-dimensional omnidirectional flexible positioning
Five equally spaced positioning holes (D16/D28 are the mainstream) are provided, supporting arbitrary position fixation of X/Y/Z axes, and suitable for irregular, multi-weld seam, and spatially intersecting structural components (such as automotive chassis, aviation frames, and construction machinery arms). Modular accessories (V-blocks, angle devices, quick clamps) enable 0–360° angle adjustment, meeting the requirements for complex joint welding positioning.
-
High precision and high rigidity
The center tolerance of the positioning holes is ±0.05mm, the flatness is ≤0.02mm/m (precision grade), the repeat positioning accuracy can reach ±0.03mm, ensuring the consistency of weld seams of complex parts. The main body is made of HT300 cast iron / Q345 alloy steel, which undergoes high-temperature aging + natural aging to eliminate stress, with a deformation of ≤0.5mm under a 2-ton concentrated load, and a deformation of <0.024mm under an evenly distributed load, with strong vibration resistance.
-
Quick change and expandability
The single pin bolt rotates and locks, generating 5 tons of clamping force and 25 tons of shear resistance force, reducing the assembly time from traditional several hours to 15–30 minutes. Supports multi-platform connection and can be expanded to super-large worktables (such as 4000×2000mm), suitable for welding of wind turbine towers, large steel structures, etc., of super-sized components.
-
Long service life and low cost
The surface is treated with nitriding / quenching, with a hardness of HV600–800, the wear resistance is 3–5 times that of ordinary carbon steel tables, the modular design facilitates the replacement of accessories, avoiding the scrapping of the entire machine.

Maintenance and Repair Guide
- Prohibition of using high-intensity grinding tools: Do not use high-intensity grinding tools such as angle grinders or sandpaper to grind the surface of the workbench, as this may damage the nitrided layer and flatness of the workbench.
- Prohibition of overloading: Strictly operate within the rated load capacity of the welding table. Overloading can lead to workbench deformation, fixture damage, and even safety accidents.
- Prohibition of using non-standard fixtures: Only use LEMAR original matching fixtures or European standard fixtures that meet the hole system standards to avoid wear or deformation of the positioning holes caused by non-standard fixtures.
- Compliance requirements: For European customers, the anti-rust oil, slag remover, and other chemicals used during maintenance must comply with REACH regulations and CE certification requirements to avoid product use issues due to environmental concerns.
