Example Embodiment
[0045] Figure 1a A schematic representation of a first exemplary embodiment of the device 1 according to the invention for carrying out the first exemplary embodiment of the method according to the invention during warm-up is shown. The device 1 is used for resistance welding a sandwich panel 2 to at least one other, for example metallic, component 4 . The sandwich panel 2 has a thermoplastic layer 2c arranged between the metallic covering layers 2a, 2b. The device has a first welding electrode 6 arranged on one side of the sandwich panel 2 and a second welding electrode 8 arranged on one side of the other metallic component 3 .
[0046] Furthermore, the means for providing the first electrical circuit is provided with a first power source 10 and a first electrical line 12 . The current Is for welding can thus be conducted through the first welding electrode and the second welding electrode 6, 8 (at figure 2 are shown in).
[0047] Furthermore, the first welding electrode...
