ResumoIn all types of friction welding the joining process is started by the generation at the rubbing interface of frictional heat arising from the relative motion of the components. In one form of orbital friction welding the two components to be joined are rotated about their longitudinal axes in the same sense with the same constant angular speed: the two longitudinal axes being parallel but offset by a small distance. The interfacial rubbing velocity so created is particularly simple and in this paper a general expression for the rate of heat generation at the rubbing interface during the early stages of the orbital friction welding process is presented. The particular cases of a pair of rods of circular cross-section and two rods of square cross-section are considered in some detail.
