D28 Steel 3D Welding Table - High Hardness and Wear Resistance

The D28 Steel 3D Welding Table is a modular and flexible fixturing system designed for heavy-duty/precision welding, assembly, and inspection applications. It features a core system of φ28mm standard positioning holes and utilizes high-strength alloy steel with a deep surface hardening process to achieve high hardness, wear resistance, deformation resistance, and resistance to welding slag adhesion. It is specifically designed for heavy workpieces, large structural components, and high-throughput welding production lines.

• High Hardness and Deformation Resistance: Alloy steel base material + deep hardening process, surface hardness reaches HV550+, ensuring no deformation or collapse under long-term heavy loads, solving the problem of deformation and accuracy degradation in traditional welding tables.
• High Wear Resistance and Weld Slag Resistance: The dense and wear-resistant nitrided oxide composite layer allows weld slag to easily detach after cooling, eliminating the need for forceful grinding. The edges of the holes do not wear into a flared shape, ensuring long-term stable positioning accuracy; workpieces can be dragged across the surface without scratching, extending the service life by more than 3 times.
• D28 Large Hole System for Heavy-Duty Applications: Compared to the smaller D16 specifications, the D28 hole system offers stronger load-bearing capacity and wider fixture compatibility. It can accommodate heavy-duty positioning blocks, V-blocks, support blocks, etc., meeting the welding needs of large workpieces in steel structures, construction machinery, pressure vessels, and other industries.
• Modular and Flexible Expansion: 5-sided precision milling + standard hole system allows for seamless splicing of multiple units, enabling quick switching between different workpieces and fixtures without the need for custom fixtures, significantly shortening changeover time and reducing tooling costs.
• All-Scenario Adaptability: Compatible with multiple processes including manual welding, robotic welding, assembly, and inspection, suitable for industries such as automotive manufacturing, construction machinery, steel structures, rail transit, and pressure vessels.

• Complete Factory Audit Documentation Package: Includes production process flow charts, individual precision/hardness test reports for each piece of equipment, raw material procurement certificates, employee skills training records, workshop environmental management documents, and quality control system documents;
• OEM/ODM Private Labeling: Customer's brand logo, product model, and production batch number can be laser engraved or silk-screened onto the tabletop and frame according to customer requirements. Neutral packaging without original manufacturer markings is supported;
• Full Process Traceability: Each piece of equipment comes with a unique traceability code. Scanning the code allows access to information on the entire production, testing, packaging, and shipping process, meeting the quality control and traceability requirements of large clients;
• Remote/On-site Factory Audit Support: We provide real-time video of the workshop production site and high-definition photos of equipment production details to assist customers in completing remote factory audits. If the customer conducts an on-site factory audit, we can arrange for a professional engineer to provide a full explanation and demonstrate the testing equipment on-site.
