The 28 Series Welding Table with High-Load Bearing Frame is a modular fixturing platform designed for high-load, high-precision, and high-volume welding applications in heavy structural components, construction machinery, rail transit, shipbuilding, and large sheet metal fabrication. Its core features include a φ28mm standard hole pattern, 100mm × 100mm hole spacing, and a high-strength, heavy-duty support frame.

Heavy-duty framework (core competency)

• Structural Design: Box-type fully welded frame with dense reinforcing ribs; the main body is made of Q355/HT300 material, subjected to vibration aging/annealing stress relief, ensuring excellent torsional, bending, and impact resistance, preventing frame deformation and accuracy degradation under long-term heavy loads.
• Support System: Standard configuration includes 4-8 heavy-duty support legs (single leg load capacity ≥2.5t), equipped with precision leveling feet (leveling accuracy ±0.02mm); optional heavy-duty casters (with brakes) are available for easy movement and layout adjustment on the production line; extra-large tabletops can be fitted with intermediate support columns to further increase the load capacity.
• Splicing Design: High-precision positioning pins + locking mechanism ensure that the overall accuracy of multiple spliced ​​units is consistent with that of a single unit, suitable for batch clamping and welding of extra-long/extra-large workpieces (such as engineering machinery frames, ship sections, and wind turbine tower components).

Tabletop and hole system (precision and versatility)

• Hole System Advantages: φ28mm large hole diameter + 100mm large hole spacing, compatible with heavy-duty positioning blocks, large-tonnage clamps, and hydraulic/pneumatic clamping components, providing clamping forces of several tons to meet the rigid fixing requirements of heavy workpieces; the hole system is precisely bored using CNC machining, with a hole spacing tolerance of ±0.05mm, ensuring repeatable positioning accuracy.
• Tabletop Performance: The surface hardness after hardening treatment is HRC45–60, resistant to welding spatter and wear, and has a service life 3–5 times longer than ordinary welding tables; the anti-spatter coating prevents spatter from adhering, requiring only a special scraper/wire brush for cleaning, resulting in extremely low maintenance costs.
• Modular Compatibility: All series of clamping components (positioning blocks, angle plates, quick clamps, support columns, vacuum/magnetic clamps, hydraulic clamping units) are 100% universally interchangeable, supporting offline pre-assembly design, and offering significantly higher changeover efficiency than traditional dedicated tooling.

Cost and Value

• Cost Reduction and Efficiency Improvement: Fixture costs are reduced by 60%-80% (no need for custom-made fixtures), labor costs are reduced by 20%-30% (simplified clamping operations), overall equipment utilization rate is increased to over 85%, welding defect rate is reduced by over 20%, and annual maintenance costs are only 1%-3% of the original equipment value.
• Long Lifespan and High Cost-Effectiveness: The 28 Series Welding Table with High-Load Bearing Frame has a design lifespan of 10-15 years, and surface hardening treatment increases wear resistance by 3-5 times. One platform can accommodate multiple workpieces, and components are reusable, resulting in an overall cost reduction of over 70% compared to traditional dedicated fixtures.
• Digital Upgrade: Sensors can be added to collect clamping force, positioning accuracy, and production data in real time, and upload it to the MES system, enabling traceability of the production process; it supports programmatic storage of clamping schemes, allowing for one-click switching between different workpiece types, helping to create a digital and intelligent welding production line.
