| Summary: | Due to its characteristics, titanium alloys are widely used in
industries such as shipbuilding, aircraft manufacturing, rocket
production, etc. Friction stir welding of titanium alloys is a
perspective method for manufacturing parts in these industries.
During the welding process, the temperature can reach more than 1200 С, while an active oxidation process occurs, which causes
defects. To eliminate the formation of voids, it is necessary to
use special devices for gas shielding. The existing devices for arc
welding are not intended for friction stir welding. The aim of the
study is to design device for supplying a shield gas during friction
stir welding of titanium alloys, which will allow eliminating these
defects. Friction stir welding of titanium alloys experiments
are carried out using the developed device. As a result of the
experiment, sound welds with no oxidation markers are produced. |
