The 3D flexible welding platform (Welding Table, Welding Workbench)is an advanced modular tooling system composed of a work surface with a standardized grid of holes, various positioning modules, and quick-clamping mechanisms. Based on the principle of hole-system positioning, this system enables rapid positioning and clamping of workpieces of different shapes and sizes through the flexible combination of standardized modules. The core design concept of the 3D flexible welding platform is to maximize the universality and flexibility of tooling, making it suitable for modern manufacturing needs characterized by multiple varieties and small batch sizes.
