D16 Heat-Treated 3D Welding Table for High Temperature Use
The D16 Heat-Treated 3D Welding Table for High-Temperature Use is a modular, flexible welding fixture system specifically designed for high-temperature welding, precision clamping, and long-term thermal stability. Its core features include a D16 standard hole pattern, integral heat treatment, and a high-temperature resistant surface treatment. It is primarily designed to maintain micron-level positioning accuracy, low deformation, high wear resistance, and splash resistance even under high-temperature conditions, making it suitable for small to medium-sized precision parts and high-temperature welding applications.

Core advantages
Extreme Thermal Stability
- Low coefficient of thermal expansion + overall stress relief ensures table deformation ≤0.03mm/m during high-temperature welding, preventing positioning accuracy drift.
- Suitable for welding processes involving continuous high temperatures and large heat input (such as welding of thick plates, stainless steel, aluminum alloys, and copper alloys).
Ultra-Hard, Wear-Resistant, and Splash-Resistant
- Nitrided layer hardness of HV900+, resistant to welding slag impact and fixture wear, resulting in a lifespan 3–5 times longer than ordinary platforms.
- The surface is non-stick to welding slag, making splashes easy to clean, eliminating the need for frequent grinding and repair, and reducing maintenance costs.
Precise and Flexible Clamping
- 50mm dense hole pattern provides 4 times more clamping points than D28 (100mm), suitable for complex, small, and irregularly shaped precision parts.
- Fixture reconfiguration can be completed in minutes, replacing 50–100 sets of dedicated fixtures, increasing production efficiency by 80%.
High-Temperature Compatibility for All Scenarios
- Withstands high temperatures from welding arcs, preheating/post-heating temperatures, and thermal cycle stress, suitable for high-end manufacturing in aerospace, automotive, construction machinery, and pressure vessels.
Installation and adaptation to the production line
Basic Requirements
- The D16 Heat-Treated 3D Welding Table for High-Temperature Use has low requirements for surface flatness and can be directly installed on hardened concrete floors or steel structures; it can be leveled using adjustable support feet at the bottom, achieving a flatness error of ≤0.08mm/m² after calibration, eliminating the need for complex foundation construction.
Automated Integration
- The table surface has standardized mounting holes, allowing for seamless integration with automated equipment such as welding robots, positioners, and turntables; it supports industrial communication protocols such as Profinet and Modbus, easily connecting to factory MES systems for real-time production data collection and traceability.
Spatial Flexibility
- Standard table sizes (1000×1000mm to 2400×1200mm) are suitable for small and medium-sized workshop layouts; multiple tables can be joined together using dedicated connecting pins to form extra-large welding platforms, meeting the welding needs of long workpieces (such as car frames and pipes).
Cost value
Direct Cost Savings:
- Replacing 50–100 dedicated fixtures saves 60%–80% on fixture design, manufacturing, and storage costs;
- Changeover time is reduced from several hours to within 15 minutes, increasing equipment utilization by over 30%.
Indirect Benefits:
- Micron-level positioning accuracy reduces workpiece rework rate to below 0.5%, saving on material and labor costs for rework;
- The D16 Heat-Treated 3D Welding Table for High Temperature Use is suitable for multi-variety, small-batch production, enabling quick response to customer customization needs and enhancing the company's order-taking capabilities.
