Abstract:
The invention relates to a device and to a method for homogeneously welding two-dimensionally bent structures by friction stir welding.

Claim (Index 1):
A device for homogeneously welding two-dimensionally bent structures in the form of at least two mating partners ( 6 ) by friction stir welding, the device having the following features:\n a) a receptacle plate ( 1 ) that is guided by a guiding machine and has a drive head ( 2 ) and a tool dome ( 3 ) that is fastened to said drive head ( 2 ) and has a welding shoe mounting ( 4 ) and a pin bearing ( 5 ) for a welding pin ( 11 ) of a welding shoe ( 8 ); b) the welding shoe ( 8 ) has a circular basic shape on which a transverse web is located, the latter running across the cross section of and orthogonally to said basic shape, said transverse web having approximately the width of \u00bc to \u2155 of the diameter of the basic shape and having an arcuate shoe gliding face and shoe smoothing face, wherein a small planar face in the form of a notch-type taper, the chip-guiding step ( 9 ), is located on the front side of this face, in the region of the periphery of this face, and wherein the shoe gliding face and the shoe smoothing face corresponds substantially to the surface curvature of the mating partners ( 6 ); c) the tool dome ( 3 ) has a strip-shaped sensor ( 23 ) which is configured for determining force, pressure, or travel and is attached to that side of the tool dome ( 3 ) that is opposite to the flow direction of the welding process, and wherein a cone constriction ( 17 ) is provided in the comparatively wide region of the tool receptacle cone ( 26 ), said cone constriction ( 17 ) serving for receiving a sensor ( 20 ) for acquiring the axial force, the torque, and the bending momentum on the welding pin ( 11 ), and wherein a further constriction in the front region of the tool receptacle cone ( 26 ) having at least three sensors ( 25 ), distributed at a spacing of 120 degrees on the circumference, for measuring the axial force that acts on the welding pin ( 11 ), and having a piezoelectric force measuring sensor ( 24 ), likewise for measuring the axial force, is provided in the longitudinal axis of the shaft ( 7 ) of the friction pin, and wherein a sensor signal amplifier having a rotary antenna ( 21 ) for receiving, for amplifying, and for transmitting all acquired measured values is provided, wherein these measured values are transmitted from a static antenna ( 22 ) to a machine controller, and wherein an induction power supply system for supplying the measuring system from a moving secondary coil ( 19 ) and from a fixed stationary primary coil ( 18 ) is provided.
