Dongfeng Kinland Vehicle floor welding assembly 5100010-C0302

The assembly features advanced robotic MIG (Metal Inert Gas) welding—an automated process that ensures consistent, high-quality weld joints across all connection points. Each weld is inspected for penetration depth (minimum 80% of material thickness) and freedom from defects (e.g., porosity, cracks, or incomplete fusion), adhering to Dongfeng Kinland’s strict OEM welding standards. This precision welding creates a monolithic structure that eliminates weak points, ensuring the floor assembly aligns perfectly with the truck’s chassis rails, cabin mounting brackets, and undercarriage components. The welded joints also enhance the assembly’s torsional stiffness, reducing cabin flex during cornering or uneven road surfaces—improving driver comfort and long-term durability

Exclusively engineered for specific Dongfeng Kinland truck models (e.g., heavy-duty tractors, dump trucks), the 5100010-C0302 floor assembly is designed to match the exact dimensional specifications of the vehicle’s chassis and cabin. It includes pre-punched mounting holes (for cabin seats, floor mats, and wiring harnesses) and integrated recesses (for fuel lines, brake tubes, or electrical conduits) that align with the truck’s factory routing. The assembly’s perimeter edges are precision-trimmed to fit seamlessly with the cabin’s side panels, front firewall, and rear bulkhead—eliminating gaps that could allow water, dust, or noise intrusion. This tailored fit ensures plug-and-play installation during vehicle production or replacement, reducing assembly time and minimizing the need for on-site modifications

To withstand harsh environmental conditions (e.g., road salt, moisture, and industrial dust), the floor welding assembly undergoes a multi-step corrosion protection process. First, the steel surfaces are treated with a phosphate coating (to enhance paint adhesion and prevent rust). Next, a cathodic electrophoretic coating (E-coat) is applied—an immersion process that creates a uniform, corrosion-resistant film (8-12μm thick) covering all exposed surfaces, including weld joints and recesses. Finally, critical underbody areas (prone to stone chips or water accumulation) receive an additional layer of anti-gravel paint (15-20μm thick). This triple-layer protection ensures the assembly resists rust and degradation for over 8 years of standard use, even in coastal or cold-climate regions where road salt is prevalent

The 5100010-C0302 floor assembly is designed with integrated functional elements that enhance its utility in heavy-duty truck operations. It includes reinforced mounting pads for cabin seats (with welded steel inserts to prevent bolt pull-out), drainage holes (in low-lying areas to channel water away from the cabin interior), and access panels (for easy maintenance of under-floor components like fuel filters or electrical connectors). Additionally, the floor’s top surface features a textured pattern (created via embossing) that improves grip for drivers/occupants, reducing the risk of slips when the floor is wet (e.g., from rain or spilled fluids). These integrated features eliminate the need for aftermarket add-ons, streamlining the truck’s build process and ensuring all components work in harmony with the floor assembly
