Inventors include Sato, Ippei; Nezu, Toshiyuki; and Takaseki, Yoshiyuki.
The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: The present invention provides a friction stirring rotary member with which high-strength joining can be achieved while suppressing the occurrence of joining defects, in relation to friction stir welding. Provided is stationary-type joining device for performing friction stir welding of a member to be joined, said stationary-type joining device comprising: a stage on which the member to be joined is placed; a drive mechanism which comprises an output shaft provided so as to be positioned above the member to be joined, and which is configured to rotate the output shaft; a friction stirring rotary member which is provided on the output shaft so as to rotate together with the output shaft; and a position adjustment mechanism which is configured to adjust an insertion depth of the friction stirring rotary member with respect to the member to be joined in a Z direction, where the Z direction is a direction in which the friction stirring rotary member and the member to be joined face each other. In a state in which the friction stirring rotary member is provided on the output shaft, the friction stirring rotary member generates, between the output shaft of the drive mechanism and a pin part inserted into the member to be joined during friction stirring, play that enables vibration of the pin part with respect to the output shaft.
