Welding electrode, resistance welding riveting system, resistance welding riveting system and resistance welding riveting method

摘要

The present invention relates to a welding electrode for resistance welding riveting and a resistance welding riveting plant comprising this welding electrode and a resistance welding riveting system, which in turn has the resistance welding riveting plant according to the invention. The present invention is supplemented by a resistance welding method. The welding electrode (1) comprises an electrode shaft (10) for receiving an electrode cap (30) and an electrode cap (30) which is mechanically connectable or connected to the electrode shaft (10). At least in the section (11) of the electrode shaft (10) which has the least area moment of inertia, the material constituting at least 70% of the volume of this section (11) of the electrode shaft (10) has a modulus of elasticity of at least 200 kN / mm 2.
