The invention discloses an SPS connection method for tungsten and molybdenum dissimilar refractory metals. The SPS connection method is characterized in that blocky tungsten is taken as a base body, the base body and molybdenum powder are sintered and connected through an SPS technology, so that a connecting piece of the tungsten and molybdenum dissimilar refractory metal is obtained. According tothe SPS connection method, the molybdenum powder can be sintered and compacted on the tungsten base body, meanwhile, sintering connection of the tungsten and molybdenum metals is realized, so that the connecting piece with high strength and good forming effect is obtained, and the room temperature shearing strength of a joint can reach 152.9 MPa.
