Stirring tool for friction welding, has control which uses temperature values from the welding zone acquired by a sensor arranged with a measuring site in tool pin

摘要

The sensor (7) is integrated into a telemetric measuring system (10) on the tool. Tool control uses temperature values from the welding zone acquired by a sensor arranged with a measuring site in the pin (4) of tool. Preferred Features: The system continuously sends the measured temperature values to a control and regulating unit of the tool arranged outside of the tool. The sensor is a thermocouple or a pyrometer with a sapphire rod in the pin or an optical fiber in the pin.
