Heavy Duty 3D Flexible Welding Table with Jig D28 Welding Table

Heavy Duty 3D Flexible Welding Table with Jig D28 Welding Table is a heavy-load modular welding platform built with standard D28 hole system. Designed with five-sided hole layout and complete supporting jigs, it supports 3D omnidirectional positioning and rapid clamping. The nitrided tabletop features outstanding wear resistance and stable precision, well-suited for welding and assembly of heavy structural parts and large workpieces.

Hole Diameter: Φ28mm (Precision Tolerance)

Hole Center Distance: 100mm × 100mm Standard Grid; Accuracy: ±0.05mm

Tabletop / Side Faces: 5 precision-machined working surfaces (top surface + four vertical faces); the entire hole pattern is interconnected, allowing for 3D extension of fixturing setups.

Base Material: Q355 High-Strength Steel / HT250 Cast Iron

Surface Treatment: Nitriding (Hardness: HRC 42-52); provides resistance to wear, welding spatter, rust, and high temperatures, significantly extending service life.

Structural Design: Bottom Reinforcement Ribs + Box-Type Structure; ensures no deformation under heavy loads.

• Work Surface: A five-sided platform featuring a precision hole pattern, complete with millimeter scales and coordinate lines to facilitate precise measurement and positioning.
• Reinforced Base: Constructed with an integrally welded rib structure, providing exceptional resistance to vibration and deformation.
• Support Legs: The 3D welding table offers a choice of support options—fixed legs, adjustable leveling feet, height-adjustable legs, or mobile legs with casters—to accommodate various workshop floor conditions and mobility requirements.

• Heavy-Duty Durability: Constructed from high-strength materials treated with a nitriding process, offering exceptional resistance to welding spatter and high temperatures while maintaining stable precision over long-term use.
• 3D Flexibility: Featuring a five-sided hole pattern system combined with a comprehensive range of modular fixturing components, this system eliminates the need for custom-fabricated, dedicated tooling.
• High-Precision Positioning: Boasting high accuracy in hole positioning, surface flatness, and perpendicularity, the system ensures consistent and repeatable welding results.
• Efficiency and Cost Savings: Enables rapid clamping and quick changeovers between setups, thereby boosting welding efficiency and significantly reducing investment in specialized tooling.
• High Versatility: Adhering to the global D28 standard interface, the system ensures full interchangeability and expandability of fixtures, allowing multiple tables to be seamlessly joined together to create large-scale work platforms.

• Slight deformation/out of tolerance flatness of the countertop
  Reason: Overloading, long-term local compression, and insufficient timeliness.
  Solution: Use with light load, re level; Minor deviation manually scraped and repaired, severe return to factory for calibration.
• Hole jamming and improper insertion and removal of fixtures
  Reason: Accumulation of slag and corrosion inside the hole.
  Solution: Clean the holes with compressed air and apply anti rust oil; Polish the hole wall with fine sandpaper for slight rust.
• The support feet of the 3D welding table are loose and the platform is shaking
  Reason: Failure to lock the anchor bolts and ground subsidence.
  Solution: Re level and tighten the bolts; Add cushion plates for reinforcement in areas with soft ground.
• Welding slag adhesion on the surface of the welding table is difficult to clean
  Reason: Failure to pad fireproof board and direct contact with high-temperature slag.
  Solution: After cooling, use a specialized shovel to gently shovel and strictly prohibit hammering with a large hammer; Fireproof pads must be installed in the future.

Globally Compatible: Our welding tables comply with DIN and ISO standards, ensuring universal interchangeability with D28 accessories worldwide.

Standard Factory Inclusions: Material Analysis Certificate, Precision Inspection Report, and ISO 9001 Quality Certification (a prerequisite for reputable manufacturers).
