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

Claim (Index 3):
A method for homogeneously welding two-dimensionally bent structures in the form of at least two mating partners ( 6 ) by friction stir welding, the method 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 ) serves for carrying out the method; b) in order for a welding result that is free of holes and has a flawless surface to be achieved on both sides of the mating partners ( 6 ), the measured parameters that are relevant for controlling the welding process are determined, wherein a strip-shaped sensor ( 23 ) is provided along the side of the tool dome ( 3 ) for detecting force, pressure, or travel, wherein a sensor ( 20 ) for acquiring the axial force, the torque, and the bending momentum on the welding pin ( 11 ) is provided, wherein at least three sensors ( 25 ) in the form of strain gauge strips that are distributed on the circumference of the tool receptacle cone ( 24 ) serve for measuring the axial force acting on the welding pin ( 11 ), and wherein a further piezoelectric force measuring sensor ( 24 ) is provided in the longitudinal axis of the shaft ( 7 ) of the friction pin, said piezoelectric force measuring sensor ( 24 ) likewise serving for measuring the axial force.
