D28 Steel Nitriding Welding Table

The D28 Steel Nitriding Welding Table is a high-performance, heavy-duty industrial workbench engineered for precision welding, assembly, and fabrication applications across metalworking, automotive, aerospace, and heavy machinery industries. Crafted from premium D28 structural steel with advanced nitriding surface treatment, this table redefines durability, dimensional stability, and welding accuracy, serving as a reliable core workstation for professional welding operations.

At the heart of this table is its D28 steel base—a high-strength low-alloy steel renowned for excellent load-bearing capacity, impact resistance, and structural rigidity. The material’s inherent mechanical properties ensure the table can withstand the extreme thermal stress, welding spatter, and heavy workpiece loads common in industrial welding, avoiding deformation or structural failure even under long-term continuous use. What elevates its performance further is the professional gas nitriding surface treatment applied to the entire working surface and frame. This thermochemical process diffuses nitrogen into the steel’s surface layer, forming a dense, hard nitrided layer (surface hardness up to HV 800-1000) that delivers exceptional wear resistance, corrosion resistance, and anti-seizure performance. Unlike traditional paint or plating treatments, the nitrided layer bonds metallurgically with the base steel, eliminating peeling, chipping, or fading—even after repeated welding, grinding, and cleaning.

The welding table features a precision-machined working surface with standard modular fixture holes (D28 round holes as the core specification) distributed in a uniform grid pattern. The high-precision hole position tolerance (≤±0.05mm) ensures seamless compatibility with a full range of modular welding fixtures, including clamps, supports, locators, and positioning pins, enabling quick and accurate fixture setup for complex workpiece welding. This modular design drastically reduces fixture changeover time, improves welding efficiency, and ensures consistent dimensional accuracy across batch production. The flatness of the working surface is strictly controlled to ≤0.02mm/m, eliminating welding errors caused by surface unevenness and guaranteeing the precision of welded workpieces.

In structural design, the D28 Steel Nitriding Welding Table adopts a reinforced frame structure with thickened steel plate welding and integral stress relief treatment. The stress relief process eliminates internal residual stress generated during manufacturing, preventing structural deformation due to temperature changes during welding and ensuring long-term dimensional stability. The table’s frame is designed with optimized load distribution, supporting a uniform load capacity of up to several tons (customizable according to user requirements) and accommodating large, heavy workpieces such as steel structural components, automotive chassis, and mechanical parts. For enhanced practicality, the table is equipped with anti-slip adjustable foot pads, which can fine-tune the level of the working surface to adapt to uneven factory floors and absorb welding vibration, further improving welding stability.

The surface of the nitrided welding table is non-porous and smooth, making it easy to clean and maintain. Welding spatter, slag, and metal dust can be quickly removed with a wire brush or cleaning agent without damaging the surface layer; the corrosion-resistant nitrided surface also adapts to harsh factory environments, including high humidity and oil contamination, reducing maintenance costs and extending the table’s service life (up to 10+ years under normal use).

Available in a full range of standard sizes (1000×1000mm, 1500×2000mm, 2000×3000mm, etc.) and customizable dimensions, the D28 Steel Nitriding Welding Table can be tailored to the specific needs of different workshops and production lines. It can also be integrated with auxiliary equipment such as welding positioners, dust removal systems, and lighting fixtures to form a complete welding workstation.

As an essential piece of equipment for modern precision welding production, the D28 Steel Nitriding Welding Table combines high-strength material, advanced surface treatment, and precision structural design. It not only improves welding efficiency and workpiece precision but also reduces production costs and equipment downtime, making it an ideal investment for manufacturing enterprises pursuing high-quality, high-efficiency metal fabrication.
