Abstract: A double-head double-sided high-efficiency friction stir welding device includes a base (1), a pair of columns (2) arranged on the base (1), an upper beam (3), at least one worktable connected with a horizontal surface of the base (1), vision sensors (7) mounted on the upper head (5) and the lower head (6) and used for identifying the weld, and a CNC controller (8) used for controlling operations of the gantry, the upper head (5), the lower head (6), the worktable and the vision sensors (7).

Abstract: A die mechanism comprises a first support member and a second support member, the first and second support members extending in a first direction; a plurality of pin modules between the first and second support members, wherein each of the plurality of pin modules extends in a second direction perpendicular to the first direction, and each pin module comprises a plurality of pins; wherein heights of ends of the plurality of pins within each of the plurality of pin modules together define a shape profile for shaping the component during creep-age forming; and wherein: the plurality of pin modules are configured to be movable along the first and second support members in the first direction, and/or the plurality of pins are configured to be movable along respective pin modules in the second direction.
