D28 Heavy Welding Worktable

1. Heavy-Duty Load Capacity & Stable Structure

Made of Q355 high-strength steel or HT300 cast iron, the worktable adopts a full-box structure with dense reinforced ribs inside, ensuring uniform load capacity up to 3000kg/㎡ and concentrated load up to 5 tons per single point. After high-temperature stress relief annealing, it effectively resists welding thermal deformation and impact, maintaining long-term precision without warping even under 24-hour continuous welding.

2. High-Precision 3D Positioning System

Φ28mm precision positioning holes with 100×100mm grid spacing, hole pitch tolerance ±0.05mm, table flatness 0.1-0.3mm/m, and verticality ≤0.1mm/200mm. 5 working surfaces (top + 4 sides) support X/Y/Z three-dimensional clamping, suitable for irregular workpieces, round pipes, frame and box welding, ensuring consistent product size and reducing rework rate by 30%.

3. Flexible Modular Fixture Ecosystem

Full set of D28 standard accessories (pins, clamps, angle blocks, V-type brackets, extension connectors) are interchangeable, no need to make special jigs for each workpiece. Mold change can be completed in 5-15 minutes, saving 70% of jig production cost for small-batch and multi-variety production.

4. Durable Surface Treatment & Environmental Protection

Optional plasma nitriding treatment (0.25-0.35mm hard layer, surface hardness HV450-630), which is wear-resistant, anti-spatter and rust-proof, with salt spray resistance of 500 hours, suitable for coastal and high-dust workshops. The nitriding process is environmentally friendly, meeting EU environmental protection standards without acid-base pollution.

5. Unlimited Splicing & Multi-Scene Adaptation

Multiple worktables can be seamlessly spliced into 10m+ long working areas with splicing connectors, suitable for welding of extra-long workpieces such as truck girders and container frames. 3 types of support legs (fixed, mobile, hydraulic lifting) are optional, adapting to fixed workshops, multi-station circulation and robotic welding workstations.
