The welding fixture is a special equipment that constrains the welding workpiece through a mechanical structure. Its core function is to achieve accurate positioning and firm clamping of the workpiece during welding, thereby effectively controlling welding deformation. According to different industrial application scenarios, welding fixtures can be divided into pipe welding fixtures, automotive parts fixtures, sheet metal anti-warping fixtures and other types. Modern welding fixtures generally adopt a modular design, including three core modules: clamping components, transmission mechanisms and positioning devices. Precise control of clamping force is achieved through gear plate meshing, hydraulic drive and other technologies.
