A vehicle typically consists of several thousands of spot joints such as rivets, clinch joints or spot welds. They are used to bond together different parts of the vehicle. But the rivets are costly and do not have great strength. Moreover, spot joints require a certain sheet thickness to provide sufficient strength. Researchers in Sweden have now invented a welding tool that also functions as a temperature sensor.
