ABSTRACT:
In order to control the cooldown temperature of a weld produced by a friction welding process, an electrical signal having a low voltage and a high current is passed through the weld thereby providing desired metallurgical properties. The weld acts as a resistor due to its high temperature as compared to the surrounding material such that the current causes the weld to heat up when the current passes through the weld and also causes the electrical signal to change as it passes through the weld. The change in current can be measured and the temperature of the weld can be controlled which allows the cooldown of the weld to be properly maintained for the desired metallurgical properties.
