Lighter cars with new robotic welding method

Researchers invented a welding tool that also functions as a temperature sensor. The temperature is measured continuously and, if it becomes too hot, the heat is regulated by controlling the force and tool rotation. The researchers have also made use of an industrial robot to perform the welds and achieve a constant welding quality.
