Assembly Welding Table Multi-Purpose Welding and Clamping Workstation 16/28mm System 1500*2000*200 Nitrided Q355 is a modular and multi-functional welding and assembly workstation. It is made of Q355 high-strength steel with nitriding treatment, and is compatible with both D16 and D28 positioning hole systems. It is suitable for various industrial scenarios such as welding, assembly, and inspection. Its core advantages lie in the dual-aperture design and high-rigidity structure, which can meet the full-size operation requirements from precision small parts to large structural parts.

(1) 16/28mm aperture system
• D16 hole system: Used for positioning precision small parts (such as automotive electronic brackets, hydraulic valve blocks)
• D28 hole system: Used for fixing heavy-duty structural parts (such as construction machinery frames, steel structure beams)
• Hybrid grid layout: The two hole systems are distributed as needed to avoid spatial conflicts
(2) Nitrided Q355 steel
• Ultra-high surface hardness: Nitrided layer depth is 0.3 - 0.5mm, resistant to fixture wear and welding spatter
• Corrosion resistance: The acid and alkali resistance is 50% higher than that of ordinary Q355 steel
• Thermal stability: Almost no thermal deformation below 300ºC
(3) Multifunctional expandability
• Assembly mode: Measuring instruments can be installed for accuracy inspection
• Welding mode: Compatible with robot automated welding (interface module needs to be selected)
• Fixture compatibility: Supports the mixed use of mechanical/pneumatic/magnetic fixtures
(4) Ergonomic optimization
• Edge T-slot design: Facilitates the installation of guardrails or lighting systems
• Lifting interface: Lifting holes are reserved at the four corners (maximum load-bearing 2 tons per point)
We have many different product for your recommend!
Typical application scenarios
• Automotive mixed production line: Simultaneously welding thin body panels (D16 positioning) and heavy chassis parts (D28 positioning)
• Construction machinery assembly: Such as welding and dimensional verification of excavator booms
• Aerospace: Hybrid assembly of composite and metal structures
• Mold repair: Using high-precision hole systems for reverse engineering positioning
Precautions for model selection
1. Confirm the size distribution of workpieces: If more than 80% are heavy parts, it is recommended to select D28 as the main model.
2. Nitriding layer inspection: Require the supplier to provide a hardness test report (with at least 3 - point inspection).
3. Expansion requirements: Reserve at least 10% of the tabletop space for future additional fixtures.
