Abstract
In order to determine the temperature of a weld produced by a friction welding process, an electrical signal having a low voltage and a low current is passed through the weld. The weld acts as a resistor due to its high temperature as compared to the surrounding material such that the current in the electrical signal changes after its interacts with the weld. The change in current can be measured and the temperature of the weld can be determined.
