Method for the resistance welding of components with a variable progression over time of the welding current, and component composite produced thereby

The invention relates to a method for the resistance welding of components (110, 120), wherein a compressive force is applied to the components (110, 120) at the welding point by means of electrodes arranged on both sides of the components (110, 120) and the components are welded to one another, whi...

Beschreibung
Zusammenfassung:	The invention relates to a method for the resistance welding of components (110, 120), wherein a compressive force is applied to the components (110, 120) at the welding point by means of electrodes arranged on both sides of the components (110, 120) and the components are welded to one another, while forming a weld nugget (140), by means of a welding current passed via the electrodes. According to the invention the welding current has a variable progression over time that is distinguished by alternating high-current energizing phases and low-current or current-free cooling and solidifying phases, whereby a weld nugget (140) is formed by a number of interlayered and/or adjacent melt zones (132, 133). The invention also relates to a component composite (110/120) produced by this method.
