The key feature of this large-scale granite platform is its large size and high load-bearing capacity, suitable for positioning and welding of large mechanical components. The multi-grid T-slot design allows for flexible installation of various welding fixtures, adapting to different types and sizes of workpieces. Unlike traditional steel welding platforms, it does not generate sparks or magnetic interference during welding operations, avoiding damage to the workpiece surface and ensuring welding quality. Its surface is treated with heavy-duty grinding and polishing, providing a flat and smooth reference plane for welding positioning, and is easy to clean after welding slag and dust accumulation.
This large-scale granite platform has a workbench size of 2000mm in length, 1500mm in width, and 200mm in thickness, with a flatness tolerance of 5μm per 1000mm for 0-grade precision. It is equipped with 4 rows of T-slots with a width of 20mm and a pitch of 150mm for fixing standard welding fixtures. The maximum static loading capacity is 10000kg, and the total weight is 1800kg. The linear expansion coefficient is 5.0×10^-6/℃, maintaining stable performance within a temperature range of 10℃ to 35℃. It is packaged in a split reinforced wooden crate to facilitate transportation and on-site assembly, and each unit comes with a calibration certificate valid for 12 months.
This large-scale welding fixture granite platform is mainly applicable to heavy machinery manufacturing workshops, shipbuilding yards, steel structure processing plants, and large-scale metal component welding workshops. It can be used as a positioning benchmark for welding of large mechanical equipment components, ship hull segments, and steel bridge structures, providing accurate positioning and flatness reference for welding operations. It helps enterprises improve welding accuracy, reduce post-welding correction workload, and shorten production cycles.
