Product Description
D28 3D Welding Table for Pipe and Structural Steel Fabrication
The D28 3D flexible welding table is a heavy-duty modular tooling platform designed for pipe assembly and heavy steel structure processing. The table surface and all four sides are machined with Φ28mm precision positioning holes, enabling multi-angle clamping and positioning of workpieces in three-dimensional space. It eliminates the need for expensive specialized welding jigs, allowing for rapid tooling switching to adapt to different workpieces. The high-load-bearing, nitrided, wear-resistant table surface is suitable for both manual welding and docking with robotic welding workstations, and is widely used for the assembly and welding of pipe flanges, H-beams, trusses, and heavy machine frames.

Product Advantages
- Heavy-duty load-bearing capacity: Static load of 5-10 tons/m², 900-1000 kg per leg, capable of supporting the self-weight of thick-walled pipes and large steel structures, and resistant to displacement under welding heat deformation
- Flexible changeover: Suitable for multi-variety, small-batch production, eliminating the need for customized welding jigs; workpiece changes only require disassembling and assembling the fixture, completing the changeover in minutes, saving on tooling design and manufacturing costs
- High repeatability and positioning accuracy: With a unified hole system datum, dimensional consistency is excellent when assembling pipes and steel structures, reducing rework such as correction and grinding
- Automation compatibility: The D28 welding table can be directly connected to welding robots to serve as a robotic welding tooling platform
Service Life & Maintenance
- Lifespan of the nitrided coating on the worktable: Under normal workshop use and standardized operation, a nitrided welding table can last 5-8 years
- Main wear areas: Φ28 hole openings. Frequent insertion and removal of the locking pins will cause the hole openings to wear slowly, resulting in decreased positioning accuracy
- Prohibited actions:
- Do not weld directly on the worktable, as the high temperature will burn the nitrided coating
- Do not grind the worktable with an angle grinder
- Do not subject the worktable to heavy impacts
- Hole wear repair: Minor wear can be repaired by replacing the locating pins; severe wear requires re-boring at the factory
FAQ
What is the delivery time for standard D28 welding tables?
Standard sizes take 15‑20 working days. Custom oversized tables require 25‑30 working days.
Do you provide inspection reports?
Yes, CMM coordinate measuring report for flatness and hole position accuracy is available upon request. CE certificate and ISO9001 are also provided.
What trade terms do you support?
We support EXW, FOB, CIF, DAP, DDP.
Can I get customized table sizes?
Yes. Besides standard sizes, we accept custom dimensions. Custom orders will take 25‑30 working days for production.
What is the warranty term?
12‑month warranty for non‑human‑caused defects. Damage from direct welding, heavy impact or improper operation is not covered under warranty.
Is the D28 welding table compatible with international System28 fixtures?
Yes, our D28 (System28) follows the same hole standard, so most third‑party System28 accessories can be applied.
