円錐台形ピンを用いて摩擦攪拌溶接を行う工具、このような工具を用いて２つの部品を溶接する方法、溶接された製品

Document Type and Number:

Japanese Patent JP7264900

Kind Code:

B2

Abstract:

The invention concerns a tool (1) intended for a friction stir welding station, the tool being capable of being rotated and comprising a body (10) defining a transverse surface forming a shoulder (11), a pin (12) extending, from the shoulder (11), along a longitudinal axis (Z) to an end (13), the pin (12) becoming slimmer between the shoulder (11) and the end, the distance between the end (13) and the shoulder (11) corresponding to a height of the pin, the pin (12) comprising a proximal portion (12p) adjacent to the shoulder (11) and extending from the shoulder (11) to the end (13) over at least 20% of the height of the pin, a distal portion (12d) adjacent to the end (13) and extending from the end (13) to the shoulder (11) over at least 1% of the height of the pin, the distal portion (12d) being inscribed in a cone frustum (14), the cone frustum (14) defining a surface, called the extension surface (15), extending the cone frustum (14) to the shoulder (11), the extension surface delimiting a frustoconical volume (16) in the proximal portion (12p), the pin extends to the outside of the frustoconical volume (16) delimited by the extension surface (15), and the pin (12) describes an outer surface inscribed in an envelope describing, in a plane parallel to the longitudinal axis (Z) and passing through the latter, in the proximal portion (12p), a profile following a curve (C), such that the curve (C) is tangential to the extension surface (15).
