AI Technical Summary
Existing H-beam welding technology suffers from poor positioning accuracy and low efficiency due to manual assembly; long welding cycles due to step-by-step welding of upper and lower welds; lack of dynamic clamping mechanism leading to warping deformation caused by welding heat input; and unstable weld quality.
The system employs intermittent web plate conveying, lifting and adsorption, simultaneous welding with dual upper and lower guns, and dynamic clamping components to achieve fully automated positioning, clamping, and welding of H-beams. A stable negative pressure adsorption is formed by an air pump and a funnel-shaped adsorption hole. The lifting cylinder precisely moves the web plate, and the multi-axis guide rail drives the dual guns to perform synchronous welding. The dynamic clamping components switch clamping modes to control deformation.
It significantly improves welding accuracy and efficiency, ensures weld quality stability, eliminates human error, shortens welding cycle, suppresses warping deformation, and improves production efficiency and weld root fusion reliability.
