Definitions

  • the invention relates to a friction stir tool for friction welding according to the preamble of patent claim 1.
  • Welding process such as the feed rate, the number of revolutions and the contact pressure of the friction stir tool. It is also known to influence them by means of cooling devices if necessary.
  • a known measuring method is to measure the temperature of the welded plates in the vicinity of the welding zone. Since the plates cool down a great deal even at a short distance from the welding zone, the temperature of the stirred material of the welding point cannot be determined with sufficient accuracy using this measuring method.
  • Welding zone temperature consists in using a pyrometer. As an optical radiation measurement, this measuring method is impaired in its measuring accuracy by the structured surface of the welding point.
  • pyrometers are also used, for example, for online testing of the quality of roll welds or pinch welds, as is described, for example, in EP 1 075 892 A2.
  • the invention has for its object to provide a friction stir tool for friction welding, which can be controlled with sufficient measurement accuracy according to the temperature in the welding zone.
  • the temperature of the welding zone is detected by means of a temperature measuring device, the measuring element of which is arranged in the pin of the friction stir tool.
  • the measuring point is only separated from the welding zone by the heat-conducting wall of the pin, and a good match can therefore be achieved between the measured and the actual temperature values of the welding point.
  • FIG. 1 shows a friction stir tool 1 in a sectional view.
  • the friction stir tool 1 for example, two butt abutting plates 2 and 3 are welded together.
  • the pin 4 of the friction stir tool is rubbed into the two plates 2 and 3 in a known manner under pressure, rotation and forward movement of the stir tool along the butt joint 5.
  • the stirred material in the welding zone 6 produced thereby forms the weld seam after cooling.
  • the stirring tool 1 is provided for receiving a temperature sensor 7 with a blind hole 8 which ends in pin 4.
  • the electrical connections of the sensor are guided via a radial bore 9 to a telemetric measuring system 10 which is arranged on the surface of the stirring tool below its clamping area.
  • the temperature sensor 7 can for example be designed as a standard thermocouple. Evaluation electronics for the thermocouple and a transmitter for the telemetric transmission of the measured temperature values to the control and regulating unit of the stirring tool, which is equipped with a suitable receiver for this purpose, are accommodated in the telemetric measuring system 10. The evaluation electronics and the transmitter are powered by a battery which is accommodated in the measuring system 10.
  • the telemetric transmission can take place by means of various methods known to the person skilled in the art; for example in the FM range, using microwaves or in the infrared range.
  • thermocouple instead of the thermocouple, a sapphire rod or an optical fiber is inserted into the blind hole 8, with which the heat radiation prevailing in the pin is optically transmitted to a pyrometer, which is recorded in the measuring system 10, and the temperature measured values feeds the FM transmitter after electronic processing.
