Method for controlling a resistance element welding process, data processing apparatus, computer program, computer-readable storage medium, and resistance welding apparatus

A resistance welding apparatus comprising:

• a first welding electrode,
• a second welding electrode,
• a resistance measuring unit connected to the first welding electrode and to the second welding electrode for providing first data (D1) indicative of an electric resistance of an assembly to be welded, and
• a data processing apparatus for:
• obtaining the first data (D1) indicative of the electric resistance of the assembly to be welded,
• comparing the first data (D1) to a resistance range, and
• causing or permitting resistance element welding of the assembly to be welded if the first data (D1) is within the resistance range,
• wherein the data processing apparatus is communicatively connected to the resistance measuring unit.
