Abstract

A friction welding tool for friction welding can be controlled with respect to measuring accuracy based upon the temperature in the weld zone. This is attained by determining the temperature values of the weld zone by way of a temperature sensor, which is arranged with its measuring point in the pin of the stir welding tool.
