Product Description
D28 Series 3D Welding Table for Efficient and Repeatable Setups
The D28 Series 3D Welding Table for Efficient and Repeatable Setups is a heavy‑modular 3D welding fixturing solution. Featuring Φ28 mm 100 mm grid holes, five‑sided bored surfaces and plasma‑nitrided surface treatment, it realizes fast and repeatable fixture setups for batch welding. It supports heavy‑load working and is interchangeable with international D28‑standard fixtures for heavy‑duty fabrication and robotic welding stations.

Product Advantages
- 3D grid hole system: The tabletop and all four sides have standard Φ 28 holes. Fixtures, positioning blocks, and clamps can be quickly installed at any position in the X/Y/Z directions without the need for customized special tooling molds.
- Repeatable: The hole position error is controlled within ± 0.05 mm. When producing the same product, the previous fixture position can be directly restored next time to ensure that the size of each batch of workpieces is consistent and reduce repeated measurement and machine adjustment.
- Efficient switching: Quick disassembly positioning pin, locking bolt, replacement of different workpieces, fixture adjustment can be completed in a few minutes, greatly reducing downtime for mold replacement, suitable for multi variety and small batch production.
- Benchmark platform: It can also serve as a benchmark for assembly and dimensional inspection.
Common Faults
Problem 1: The accuracy of the tabletop deteriorates after using it for a period of time
Reason: No stress relief and aging treatment was performed; Long term overloading; Ground subsidence; Strike the tabletop vigorously.
Solution: Re CNC milling to repair flatness; Do not strike or cut directly on the table.
Problem 2: Sliding thread and damaged hole of locking bolt
Reason: Excessive torque, violent tightening; There are welding slag and iron filings in the hole that have not been cleaned.
Solution: Clean the iron filings in the hole before each installation; Lock with a torque of 80-100N * m; Damaged holes can be repaired with inserts.
Problem 3: Welding slag sticking to the tabletop
Solution: Nitriding layer can reduce adhesion, but it cannot completely eliminate it; Do not use a hammer to strike the welding slag, as it will damage the nitride layer; Use a copper shovel to clean.
Problem 4: Misalignment of the splicing table
Reason: No splicing positioning pin was used; There is no overall leveling after splicing.
Question 5: Misunderstanding that D28 is suitable for very small parts
The hole spacing of D28 welding table is 100mm, and the positioning accuracy of small hole parts is not as good as D16 (50mm hole spacing), so D16 welding table is preferred for small parts.
FAQ
Q: Can I use existing Siegmund/Demmeler fixtures on your D28 table?
A: Yes, our D28 hole system is fully interchangeable with international standard D28 fixtures.
Q: What is the recommended tightening torque for locking bolts?
A: 80‑100 N*m. Do not over‑tighten to avoid thread damage.
Q: How often should I re‑level the table?
A: Check level every 3‑6 months, especially if workshop floor has settlement.
Q: Can multiple D28 welding tables be spliced for extra‑large workpieces?
A: Yes, we supply special splicing locating pins for alignment. Whole assembly needs re‑leveling after splicing.
Q: What documents will you provide for export?
A: CE certificate, material certificate, inspection report, packing list, commercial invoice, and outgoing inspection video on request.
