1. Preparation method of only one first component or a plurality of first components of electrically conductive or non-conductive material by providing a welding auxiliary joining part therein to a later fastening to at least a second component of weldable material or having a portion of weldable material by a later welding of the welding auxiliary joining part to the at least one second component, wherein the preparation method comprises the following steps:
a. driving of the welding auxiliary joining part into the only one first component or the plurality of first components with a combined mechanical-thermal load acting on at least the welding auxiliary joining part, wherein no waste material is separated from the only one first component or the plurality of first components, and
b. deforming the welding auxiliary joining part under combined mechanical-thermal load at a die at an exit location out of the only one first component or out of the plurality of first components so that a weld head of the welding auxiliary joining part is created,
c1. the only one first component or the plurality of first components consists of an electrically non-conductive material and the welding auxiliary joining part is driven in by an electrode punch and is guided by an electrode blank holder, wherein the electrode punch and the electrode blank holder have different electrical polarities so that a current flows between electrode punch and electrode blank holder via the welding auxiliary joining part which heats at least the welding auxiliary joining part, or
c2. the only one first component or the plurality of first components consists of an electrically conductive material and the welding auxiliary joining part is driven in by an electrode punch and is guided by an electrode blank holder which is electrically insulated with respect to the welding auxiliary joining part, wherein a supporting electrode die is electrically insulated.
