AI Technical Summary
In the existing technology, the welding quality of grid assemblies for nuclear reactors is unstable, the efficiency is low, and it is difficult to guarantee the flatness and verticality requirements. In particular, manual argon arc welding is difficult to meet the flatness requirements of ≤2.5mm and the verticality requirements of ≤3mm.
Micro-spherical tooling and clamping tooling are used for pre-deformation assembly of grating plates. Combined with robotic arm automatic MIG welding and laser tracker measurement, the precise positioning and automatic welding of grating plates are achieved. Welding deformation is controlled by adjusting the welding sequence and parameters, and cold pressing is used to ensure the final dimensions.
It effectively improved the welding quality and efficiency of grid components, ensured the flatness and verticality requirements, solved the shortcomings of traditional manual welding, and realized high-precision processing of grid components for nuclear reactors.
