The System 28 5'x5' (60"x60") Welding Table with Plasma Nitration is a professional-grade modular welding workbench. Its key feature is the tabletop, which is treated with a plasma nitration process, resulting in an ultra-hard, wear-resistant surface with extremely high hardness and corrosion resistance.

Principle: In a vacuum plasma environment, nitrogen atoms penetrate the surface of the workpiece to form a dense iron nitride (FeN) layer. The depth is controllable, and it does not alter the base material composition or core strength.

• Surface hardness is increased to 450–850 HV, and wear resistance is 3–5 times better than ordinary quenched steel;
• Fatigue strength is increased by 20%–40%, reducing deformation and cracking caused by welding thermal stress;
• The nitrided layer is dense and non-porous, and its corrosion resistance is significantly better than ordinary blackening/galvanizing treatments.

Composition and Function: A special high-temperature resistant anti-welding spatter coating that is tightly bonded to the nitrided layer, providing double isolation from welding slag, oil stains, and humid environments.

• Welding slag does not easily adhere, eliminating the need for strong grinding during cleaning, thus avoiding damage to the nitrided layer;
• Reduces the use of chemical cleaning agents, lowers maintenance costs, and extends the lifespan of the workpiece by more than 30%.

The nitrided layer ensures hardness and fatigue strength, while the BAR coating strengthens anti-welding spatter and corrosion resistance, combining "hard surface" and "easy maintenance," making it suitable for high-frequency, heavy-load industrial scenarios.

• Heavy machinery manufacturing: Welding/assembly of large frames, chassis, and gearbox housings
• Aerospace: Welding of precision aluminum alloy/titanium alloy components, tooling setup
• Automotive industry: Welding of new energy vehicle battery trays, body frames, and chassis components
• Molds and steel structures: Welding of large mold bases, assembly and correction of steel structure nodes
• Military and energy: Welding of special equipment components, assembly of pressure vessel accessories

Warranty Period: A limited warranty of typically 1 to 3 years is provided, covering material defects and manufacturing issues. For plasma nitrided workbenches, a specific quality guarantee is provided regarding their hardness and wear resistance.

Accuracy Inspection and Repair: If the workbench suffers damage (such as severe impact) resulting in deviations from specified accuracy, professional on-site grinding or factory repair services are available to restore its original flatness and hole pattern accuracy.

Parts Supply: We ensure the long-term and rapid supply of all standard parts (locating pins, clamps, bolts, etc.) to guarantee the integrity and sustainability of the system.
