The efficiency of using rotary friction welding in obtaining joints from 20Cr13 steel has been evaluated. For this purpose, test samples with welded joint and from the base metal were made, and then microstructure studies and tensile tests were carried out. As part of the microstructure study, the structure of the welded joint metal and base metal was determined. As a result of tensile tests, the tensile strength, relative elongation after rupture, and fracture area were determined for the base metal and welded joint specimens. These tests have shown that friction welding can produce joints without the use of heating during welding.
