The tool for joining two material layers, from which a material layer is formed as metallic material layer by a pin, comprises a driving device (6), and a welding device (7). The driving device is designed in addition to push the pin by the two material layers. The welding device is designed in addition to weld a first portion (8) of the pin with the metallic material layer after driving the pin. The first portion of the pin is present at a front end of the pin in a driving direction. The welding device conducts a welding current through the pin. The tool for joining two material layers, from which a material layer is formed as metallic material layer by a pin, comprises a driving device (6), and a welding device (7). The driving device is designed to push the pin by the two material layers. The welding device is designed to weld a first portion (8) of the pin with the metallic material layer after driving the pin. The first portion of the pin is present at a front end of the pin in a driving direction. The welding device conducts a welding current through the pin, and welds the both ends of the pin with the respective metallic material layer. The pin is pneumatically recoverable by the two material layers. The tool is formed to bais, before driving the pin, the two material layers. The pin comprises a head at its rear end in the driving direction. An independent claim is included for a method for joining two material layers. |
