Abstract
The article presents test results concerning the high speed friction welding (HSFW) of titanium alloys Ti64 ELI and CP-Ti. In addition, the article presents tests results related to the welding process and the formation of flash. The quality of welds was assessed on the basis of non-destructive tests (visual tests) and destructive tests (static tensile tests and bend tests). The tests resulted in the identification of the correlation between HSFW conditions when joining titanium alloys, i.e. Ti64 ELI, CP-Ti, and the quality of welds. Consequently, the tests led to the determination of the optimum range of welding parameters as regards the strength of joints. 8 Ref., 2 Tabl., 6 Fig.
