Combined Assembly D28 3D Welding Table For Welding Jobs

Combined Assembly D28 3D Welding Table is a modular five-sided flexible fixture platform engineered for all heavy and precision welding jobs. Built with standard Φ28mm 100mm hole grid, this combinable welding bench allows seamless multi-table splicing to expand working space freely, delivering stable high precision across X/Y/Z three dimensions.

Available in Q355 steel, 42CrMo alloy and HT300 cast iron with optional nitrided anti-spatter surface treatment, it boasts strong load-bearing capacity, low thermal deformation and full compatibility with global D28 standard clamping accessories. Perfect for chassis fabrication, steel structure processing and robotic welding workstations, it replaces dozens of custom jigs to slash production costs, shorten workpiece setup time and guarantee consistent dimensional accuracy during batch welding production.

• Full 3D Five-Sided Working Design – Top + 4 sides all with standard D28 holes, support multi-angle clamping, vertical welding, overturn-free processing, and complex frame assembly.
• Combined & Extensible Structure – Modular splicing design, unlimited horizontal and vertical extension. Suitable for long chassis, large steel structures, and customized production lines.
• High Precision Industrial Tolerance – Table flatness: 0.3mm/1000mm, hole position tolerance ±0.03mm, ensure consistent batch welding accuracy and zero-debug repetition.
• Heavy-Duty Load Capacity – Reinforced internal rib structure, stable load 2-5 tons/㎡, support heavy mechanical parts, vehicle frames, and thick plate welding.
• Wear-Resistant Nitrided Surface (Optional) – Hardened surface up to HV450-700, anti-welding spatter, high-temperature resistant, not easy to rust or deform.
• 100% Universal Fixture Compatibility – Fully compatible with standard D28 clamping kits, positioning blocks, pins, and supports from mainstream European brands.
• Fast Changeover Production – No custom jigs needed. Reassemble modular accessories in 10-30 minutes for new products, greatly shorten lead time.

• Save Huge Jig Cost – Eliminate repeated custom fixture manufacturing. One table replaces dozens of fixed jigs.
• Improve Welding Quality – Multi-point rigid clamping effectively reduces welding deformation, ensures consistent product dimension.
• Boost Production Efficiency – Fast setup and quick changeover, greatly reduce non-production time.
• Full Compatibility – Standard D28 international hole system, all accessories universal and interchangeable.
• Long Service Life – Nitrided surface resists spatter, corrosion and high temperature, durable for 8-15 years.
• Flexible Expansion – Single or combined use, adapt to small parts and super-large workpieces.
