Anti Deformation Stabilized Structure D28 3D Welding Table

The Anti-Deformation Stabilized Structure D28 3D Welding Table is an industrial-grade modular fixturing platform designed for heavy-duty, high-precision welding applications. It is based on the D28 standard hole system for positioning and incorporates an anti-deformation stabilizing structure design to address the shortcomings of traditional welding tables, such as susceptibility to deformation, rapid loss of accuracy, and poor adaptability.

• High-Strength Base Material: The main body is made of HT300 high-grade cast iron (hardness HB170-210) or Q355 low-alloy high-strength steel. The cast iron version features low internal stress and strong thermal stability, while the steel version offers good toughness and impact resistance, reducing deformation factors at the base material level.
• Optimized Reinforcement Rib Layout: The bottom of the table features a dense, cross-reinforced rib structure + thickened frame design (tabletop thickness 23-25mm, overall thickness 100-150mm), evenly distributing welding thermal stress and heavy load pressure, preventing localized deformation.
• Full-Process Stress Relief Treatment: Through natural aging + high-temperature tempering, casting and welding internal stresses are completely released, ensuring no warping or accuracy degradation after long-term use (3-5 years), with a stable flatness of ≤0.1mm/m.
• Five-Sided Precision Machining: The tabletop and all four side surfaces are precision-milled using CNC machining, resulting in a flatness of ≤0.15mm/m, perpendicularity between the side surfaces and the tabletop of ≤0.15mm/m, and hole position center accuracy of ±0.03mm, ensuring consistent clamping datum.

• CE Certification: Complies with the EU Machinery Safety Directive (2006/42/EC), passing mechanical strength, stability, and electromagnetic compatibility tests. Allows direct access to the EU and European Free Trade Area markets, and the CE mark on packaging enhances customer trust.
• ISO 9001:2015 Certification: The entire production process complies with international quality management system standards, ensuring product batch consistency and meeting the supplier audit requirements of large European and American manufacturing companies.
• Third-Party Precision Testing Report: Provides a Zeiss coordinate measuring machine report, clearly indicating key indicators such as table flatness, hole position accuracy, and splicing errors. This provides data-driven proof of deformation resistance, which is more convincing than verbal claims.
• Material Composition Testing Report: Provides a spectral analysis report of HT300 cast iron / Q355 steel, verifying that the material meets standards and avoiding accusations of using substandard materials. This meets the raw material traceability requirements of high-end customers.
