摘要

The apparatus to avoid an interruption of the perspiration - process during friction stir welding, in particular of a breakage of the friction pin, with the following features:a) at least three in the angle of 120 degrees to each other, strip-shaped sensors (8) on the longitudinal sides of a wedge-shaped tool bell (7), wherein the tool bell (7) a schweißpin (19) by means of a tool - receiving cone (28) and a welding shoe (11) and the sensors (8) for the determination of force, pressure and path are formed,b) of a cone - waist in the lower region of the tool - receiving - cone (28) which the receiving of a sensor (22) for detecting the axial force of the torque and of the bending moment on the schweißpin (19) is used,c) of a piezo - vertical adjustment for the schweißpin (19),d) an arrangement of a laser - measuring sensor (10) in the region of the welding shoe (11) the directional effect of a round hole (27) in the area of passage of the sweeps pinspitze (12), wherein an air - sound sensor (3) the laser - measuring sensor (10) is arranged opposite to and a welding shoe - temperature sensor is provided.e) a sensor - signal amplifier (23) with a rotor - antenna for receiving, for amplification and for forwarding all the recorded measured values, whereby these measured values of a static antenna (16) are passed on to a machine control,f) an inductive power - a system for supplying the mess - system consisting of a moving secondary winding ((24) and a stationary primary winding (25).
