Research On Laser Welding Pocess Of Hualong No.1 Spent Fuel Storage Grid
The storage sleeves in Hualong No.1 spent fuel storage rack are connected by laser welds.On the basis of ensuring the full weld permeability,the welding deformation of the workpiece is effectively controlled,and the weld strength and structural accuracy requirements of the equipment are ensured.In this paper,by analyzing the process characteristics and welding parameters of laser welding,and verifying parameters through laser welding process test and evaluation,the laser welding process parameters suitable for product welding are determined.Through the analysis of the causes of various welding,the laser welding process optimization measures are proposed to ensure that the laser welding quality meets the requirements.
