| Abstract: | At the welded joint of a reactor joining the cylindrical body and the spherical sealing head without folded rim.no common tangent and transition arc exists. Huge boundary stress arises when an inner pressure is exerted in the vessel.The stress -strain relationship at the joint was analysed by elasticity,and mathematical expressions for calculating the boundary force and the boundary moment were derived to obtain the boundary stress. |

| Keywords: | sealing head inner pressure boundary stress |
