Abstract: A setting welding device is set forth for setting stud-like auxiliary joining parts in a plurality of layers of material and subjecting them to a mechanical-thermoforming process on a second layer of material and connecting them to said second layer by way of a welding operation. For this purpose, the punch is used to apply to the welding auxiliary joining part mechanical and thermal loads that follow prescribed characteristic force and current curves. Furthermore, a corresponding connecting method that can be realized with the aid of the setting welding device is also disclosed.

Abstract: A hydraulically operated setting device with a hydraulic aggregate as well as a joining method for connecting at least two components with the help of the hydraulically operated setting device is described. The cycle times compared to conventional joining methods are reduced through the targeted use of volume flows of hydraulic fluid in the prestroke chamber and the return-stroke chamber of the piston in connection with the plunger and the hold-down device chamber in connection with the plunge piston and the hold-down device.

Abstract: A setting device for connecting at least two components includes a first lever arm having a first working end, and a second lever arm having a second working end, that are pivotably connected to each other like pliers. A first linear drive is connected to the first and the second lever arm so that, by changing of the length of the linear drive, the first and second working ends can move relative to each other. A punch is arranged at a first working end that is connected to a supply module for joining elements, and/or a hold-down module.

Abstract: A welding auxiliary joining part is disclosed in the shape of a stud having a head, a shank and a tip. The welding auxiliary joining part is driven in by means of a mechanical-thermal setting method into a component of non- or poorly weldable material. During the driving in, a welding head is created due to mechanical deformation so that the component may be connected subsequently via the welding auxiliary joining part to a further component of weldable material by means of welding.
