Ajointing force dynamometer which conforms to measure the force in linear friction jointing process was designed and manufactured according to th e characteristics of linear friction jointing in this paper. The percen tage of error of the dynamometer in the x direction and y direction was 0.9% and 0.75%, respectively. The tw o directions of cross sensitivity ra nge of the dynamometer were 1.2-3.3 %. Its precision satisfies the requi rement of the dynamometer test. The TC 17 and TC11 heterogeneous titanium alloy jointing force in linear friction jointing process was tested for the manufactured dynamometer. The tested results show that the upsetting direction force is big, but the vibration direction force is smaller change in TC11 as vibration linear friction jointing process. In addition, the short jointing time linear friction jointing of the upsetting direction force and the vibration direction force is larger than the jointing time longs.
