Precision D28 Welding Table For Heavy Metal Welding Projects
Product Overview
Built to satisfy high-demanding heavy metal welding assignments, this precision D28 welding table delivers consistent positioning accuracy for tough workshop environments. Every tabletop undergoes strict CNC machining to maintain reliable flatness across the whole working surface. The standardized D28 hole layout enables fast reconfiguration of fixtures without custom tooling. It handles large, heavy workpieces steadily and cuts frequent adjustment work for metal fabricators.
Optional nitrided surface treatment greatly improves surface hardness against welding spatter and mechanical scratches. Reinforced detachable supports fit uneven factory floors and keep the whole workstation stable under heavy distributed loads. Both standard dimensions and custom-size options are available to match varied heavy-metal project requirements.

Product Advantages
Consistent Positioning Accuracy for Heavy Workpieces
CNC finished table surface holds flatness of 0.02 mm per meter. Uniformly machined D28 holes ensure smooth pin insertion and firm fixture locking. Heavy metal parts stay aligned during long welding cycles so assembly deviations get minimized.
Outstanding Weight-Bearing Stability
Manufactured from thick Q355 steel plate, the table bears static load up to 8 tons per square meter. It resists bending deformation under bulky metal components. Reinforced frame spreads pressure evenly to preserve table geometry in continuous heavy-duty shifts.
Enhanced Wear Resistance with Nitrided Option
Nitrided surface reaches hardness between 550 HV and 600 HV. It stands frequent spatter burning, scraping and abrasive contact. Less surface degradation lowers maintenance frequency and extends the service life of the whole workstation.
Flexible Fixture Reconfiguration for Variable Jobs
100-mm pitch D28 grid supports broad combinations of clamps, locating blocks and angle fixtures. Operators rebuild holding layouts quickly when switching different heavy metal projects. There is no need for expensive one-off custom jigs.
Reliable Heat Dispersion Against Thermal Distortion
Optimized plate structure dissipates welding heat across the entire tabletop. It reduces local warping caused by concentrated heat input. Original flatness can be retained after repeated high-temperature welding tasks.
Product Applications
This universal modular D28 welding table is mainly applied for fast fixture setup and welding assembly of heavy metal components. It is widely used for heavy mechanical frame fabrication, large steel structure parts processing, heavy equipment support frame manufacturing and heavy-duty cabinet production. It also works well for custom large-size metal prototype development and batch production. It can be integrated into robotic welding lines to offer stable clamping solution for bulky heavy workpieces.
- Mechanical structural component welding: Fixture assembly for heavy machinery frames, brackets and base parts.
- Automotive metal fabrication: Welding and positioning of vehicle chassis, structural supports and body assemblies.
- Pipeline and cylindrical part processing: Precise locating for pipes, flanges and circular pressure component welding.
- Frame and cabinet manufacturing: Assembly of equipment frames, metal housings and rectangular structural frameworks.
- Special-shaped workpiece production: Multi-angle positioning for irregular, radial and multi-directional metal components.
- Automated robotic welding lines: Stable tooling platform matched with robot systems for continuous batch production.
- Custom metal prototype fabrication: Fast reconfigurable tooling for trial production and small-batch customized projects.
Frequently Asked Questions
Q1: What is the surface hardness after nitriding process?
A: Our nitrided D28 welding table achieves surface hardness from 550 HV to 600 HV. Hardness inspection reports can be supplied upon formal request.
Q2: Are D28 fixtures from other brands compatible with this table?
A: Standard D28 series clamps, locking pins and positioning accessories from mainstream brands can fit our hole system normally. Minor tolerance difference from third-party suppliers may affect locking tightness.
Q3: Can I order custom table dimensions for my workshop space?
A: Custom length, width and height are acceptable. Please share your exact size requirement and workpiece weight condition so we can give feasible suggestions.
Q4: Does the product arrive as fully assembled unit?
A: Tabletop and support legs are delivered separately. Basic manual assembly is required on-site. No extra welding work is needed during installation.
Q5: What causes flatness loss of the welding table in usage?
A: Concentrated point overload, strong impact hammering and long-time local overheating will hurt surface flatness. Follow operating tips to protect your table surface.
