A device for quick and reliable tool changing in the process of friction stir welding, having the following features:

e) a robot (1) having a robotic pivoting head (2) and a friction-stir welding head (3) which is fastened to the robotic pivoting head (2), having a welding shoe (13), wherein the robot (1) in each case may select a specific friction-stir welding head (2) from a tool magazine (4);
f) a device for detecting the mechanical forces on the welding-pin tip (14) of each welding shoe (13) of a friction-stir welding head (2), wherein a sensor (16) is attached to that side of the tool bell (11) that is counter to the flow direction of the welding process, wherein a sensor (21) for measuring the torque engaging on the pin receptacle cone (26) and of the bending torque arising here is provided, and wherein furthermore a sensor (25) in the pin receptacle cone (26), and a piezoelectric force-measuring sensor (24) in the longitudinal axis of the pin shaft (27), for measuring the axial force acting on the welding-pin tip, are provided;
g) an RFDI-code for identification, attached to the pin shaft (27) of each welding shoe (13);
h) a replacement runner (28) provided on each welding shoe (13).
