Abstract

This article presents the results of a study by foreign scientists on the study of the technological feasibility of the method of friction welding of dissimilar materials. As well as information about the research work of the authors on the creation of a resource-saving, universal and affordable technology for friction welding of dissimilar materials for domestic engineering industries. The results of the study of the work of foreign scientists showed that the method of friction welding of dissimilar materials is relevant and has a wide technological capability.
It was also found that there was not used method of friction welding of dissimilar materials in the conditions of domestic engineering industries. The article presents alleged causes of this state of the problem. Considering all the shortcomings and factors identified during the study of existing methods of friction welding of dissimilar materials, the authors carried out scientific research aimed at creating a new method of friction welding of dissimilar materials. To implement the friction welding method, a design of a special device was developed and a prototype was made for experimental studies.
The article considers processes of friction welding of reinforcing bars of different diameters. It is reported that the connected reinforcing bars have passed tensile and rupture tests in laboratory conditions and in a certified test center, the results of which showed a high strength of the connection. The rupture of the rods did not occur in the welds but in the base metal.
