Welding Table D28 for Heavy Industrial Metal Welding Projects
Product Overview
This D28 modular welding table is built to handle heavy industrial metal welding projects. It is a robust multi angle fixturing platform engineered for demanding fabrication environments. The heavy steel plate undergoes stress relief processing and precision surface milling before nitriding treatment to preserve long term flatness under heavy loads and welding heat. The standard D28 hole grid allows flexible fixture arrangement across multiple working faces. Paired with compatible D28 positioning and clamping components, it simplifies workpiece setup and ensures high repeatable accuracy for large metal assemblies, heavy frame welding and industrial component fabrication.

Product Advantages
- Universal D28 hole grid enables flexible fixture layout for diverse metal frame assembly without custom jig machining.
- Nitrided table surface delivers high hardness and strong scratch resistance to withstand daily welding spatter and heavy clamping force.
- High precision machining guarantees flatness, ensuring accurate alignment for metal frames during repeated assembly cycles.
- Modular table sections can be connected together to extend working area for large sized metal frame projects.
- Adjustable support legs allow easy leveling on uneven workshop floors to keep stable working conditions.
- Compatible with full range D28 clamps, brackets and stops, reducing extra procurement cost for auxiliary tooling.
Product Applications
This D28 welding table is widely used for metal frame assembly, steel structure welding, mechanical frame fabrication, chassis prototyping, gate and railing production, and agricultural equipment component welding. It fits perfectly in job shops, metal fabrication workshops, equipment manufacturing factories and prototype development studios.
- 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.
