Product Features
- 3D Modular Fixturing System: Features a 100mm grid of D28 holes distributed across the top surface and all four sides, enabling workpiece clamping at any position in 3D space (X/Y/Z). Eliminates the need for custom welding jigs; a single platform handles various workpiece types and facilitates rapid production changeovers.
- High-Precision, Stable Base: Artificial aging relieves internal stresses from casting or welding, ensuring long-term flatness. High repeatability in positioning during assembly minimizes misalignment and reduces time spent on corrections, ensuring consistency across batch production.
- Nitrided Surface Advantages: Resistant to weld spatter and adhesion; wear-resistant and rust-resistant. Offers a significantly longer service life compared to standard painted surfaces; the preferred choice for European and American customers.
- Modular Scalability: Multiple D28 welding tables can be joined together to accommodate extra-large workpieces, with perfectly aligned holes and interchangeable fixtures.
- Optional Supports: Available with fixed heavy-duty stands or mobile stands featuring locking casters; standard height is 620mm (industrial workbench height).
Back Structure and Support System
Tabletop Underside: Steel tabletops feature a dense grid of reinforcing ribs to prevent sagging in the center of large surfaces; cast iron versions come with integral cast-in ribs.
Standard D28 welding table height: 620 mm (customizable to 750-900 mm).
Three Stand Options:
- Fixed Heavy-Duty Stand: Welded steel structure with leveling feet; recommended for high-precision applications. Leveling capability is crucial for maintaining surface flatness.
- Stand with Locking Casters: Facilitates workstation mobility. Casters must be locked during heavy-load operations; do not perform welding while the table is supported by the casters (i.e., with casters off the ground), as this can cause tabletop deformation.
- Simple Split-Type Stand: Low-cost option suitable for smaller tabletops.
Important Note: The stand serves only for support and cannot be used to correct tabletop warping; the inherent precision of the tabletop is derived from the machining and aging processes.
Product Endorsement
CE Compliance: Our D28 welding tables comply with EU Machinery Directive 2006/42/EC (CE-MD).
FAQ
Q: Can worn holes be repaired on-site?
A: Yes. Worn D28 holes can be repaired with D28 bushing inserts on site, no need to send the whole table back to factory.
Q: What is your warranty policy?
A: Warranty covers manufacturing defects such as processing error and material flaw. Warranty does NOT cover arc burning, impact damage, normal wear of holes and surface. Spare parts like bushing inserts are available for after-sales maintenance.
Q: What are your standard sizes, can you make custom dimensions?
A: Standard sizes: 1000×800 mm up to 4000×2000 mm. Custom length, width and working height are acceptable.
Q: What is the lead time?
A: Standard models 15-25 working days; custom large-size tables 25-40 working days, subject to production schedule.
Q: What packaging and shipping options are available for export?
A: We use export-grade fumigation-free wooden crates for packaging, with internal protective padding to prevent damage during transportation. For large-sized tables exceeding 4 meters, we can arrange container loading solutions (e.g., open-top containers) and provide professional loading guidance to ensure safety during sea or land transportation.
Q: Do you provide after-sales technical support for overseas customers?
A: Yes, we provide remote after-sales technical support, including installation guidance, troubleshooting, and maintenance advice. For complex issues, we can also provide video guidance. Spare parts (such as D28 bushings, locking bolts) can be shipped separately to overseas customers to ensure normal use of the welding table.
Our High Accuracy D28 Welding Table with 100mm Spacing delivers high-precision 3D flexible clamping for heavy-duty fabrication, helping you cut custom fixture costs and improve workpiece consistency.
