4'*8' D28 3D Welding Table Top with Holes TIG Welding Platform
4'×8' D28 3D Welding Table Top (4 feet × 8 feet D28 three-dimensional welding platform tabletop) is a large modular welding work platform, specifically designed for high-precision TIG welding, metal manufacturing, and complex assembly processes. This platform adopts the standard D28 hole system (28mm diameter positioning holes), combined with the 3D Adjustable fixture system, providing a stable reference plane and flexible positioning capabilities for large workpieces.
Core Features
• Extra-large working area: 4'×8' (approximately 1220mm×2440mm), suitable for welding large structural components
• D28 standard hole system: 28mm diameter positioning holes, 50mm/100mm grid distribution, with a repeat positioning accuracy of ±0.02mm
• TIG welding optimization: Magnetic-resistant and high-temperature-resistant tabletop to reduce welding deformation
• 3D adjustable system: Supports precise adjustment of the X/Y/Z three axes, suitable for complex angle welding
