Abstract: It is proposed that upon receipt of workpieces of complex shape to use the most economical technology - friction welding of workpieces. Performed analysis showed that the smaller the amount of energy required for the formation of the compound, the better its quality and higher efficiency of the process. It is shown that a steady state at the junction is preceded by a transition process, where small friction coefficients are not able to lead to plastic deformations of a relatively weakly heated metal of the butt region. The heat released is spent only on the plastic deformation of superheated metal in a very narrow layer and removed in burr. It is recommended, based on the possibility of technological equipment, to set the linear speed equal to the second critical speed, at which there is minimal burr formation.
Key words: friction welding, heating time, transition process, setting bridge, plastic deformation.
