Based on the vacuum plate glazing produced in laboratory, the residual stress field of seal edge in vacuum plate glazing caused by heat load was researched by electrometric method, and the distribution of residual stress field were successfully measured. The residual stress field of seal edge in vacuum plate glazing was analyzed by numerical calculation, and then the established mathematical model was solved by finite element method and distribution rule of its residual stress was obtained. The effect of linear expansibility and coupled stress of the solder in seal edge on the residual stress of vacuum plate glazing was discussed. The result showed that calculated and experimental results were similar. The relation between intensity of residual stress and elasticity modulus was obtained. The theoretical principle was provided for analyzing allowable value of the residual stress of seal edge in vacuum plate glazing.
