Apparatus and method for preventing interruption of the welding process during friction stir welding, in particular breakage of friction pins

摘要

The present invention relates to an apparatus and method for preventing interruption of the welding process during friction stir welding, in particular breakage of the friction pin, the apparatus comprising: g) oriented at an angle of 120 degrees to each other on the longitudinal side of the wedge-shaped tool dome 7 At least three strip-shaped sensors (8)-the tool dome (7) guides the welding pin (19) by means of a tool receiving cone (28) and a welding shoe (11), the sensor (8) being a force, Designed to determine pressure and movement -, h) the lower part of the tool receiving cone 28, which serves to receive a sensor 22 for detecting axial force, torque and bending moment at the welding pin 19 Conical constriction in the area, i) Piezo vertical adjustment for the welding pin 19, j) The laser measurement sensor 10 in the area of the welding shoe 11, and the air arranged opposite the laser measurement sensor 10 Arrangement of the airborne sound sensor (3) and the supplied welding shoe temperature sensor-the directional effect of the laser measurement sensor passes through the round hole (27) in the penetration area of the pin tip (12) -, k) detection A sensor signal amplifier (23) with a rotor antenna for receiving, amplifying and transmitting all measured values that are measured-these measured values are transmitted to the machine controller by a fixed antenna (16) -, and l) a moving secondary winding. (24) and an induction power supply system for supplying the measurement system from the fixed primary winding (25).
