Abstract
Disclosed is a friction stir welding tool with an adjustable probe length and shoulder groove depth, wherein a support shaft, made of a material having low thermal conductivity so as to inhibit thermal conduction between a probe and a shank, is coupled to the center of an upper locking member together with the shank, the probe and inner and outer shoulders are coupled inside a lower part of the upper locking member, and a lower locking member is fastened and fixed to the lower part of the upper locking member, and a washer and a locking nut are fastened to an upper part of the lower locking member, whereby the locking nut pushes the lower locking member via the washer.
Claims4
A friction stir welding tool with an adjustable probe length and shoulder groove depth, wherein
- a support shaft, made of a material having low thermal conductivity so as to inhibit thermal conduction between a probe and a shank, is coupled to a center of an upper locking member together with the shank,
- the probe, an inner shoulder, and an outer shoulder are coupled inside a lower part of the upper locking member, and a lower locking member is fastened and fixed to the lower part of the upper locking member in order to prevent separation of the probe, the inner shoulder, and the outer shoulder from the upper locking member, and
- a washer and a locking nut are fastened to an upper part of the lower locking member in order to prevent loosening of the lower locking member when the tool is rotated, whereby the locking nut pushes the lower locking member via the washer.
