Abstract in different language: This paper addresses the experimental simulation of the longitudinal HFI-welding process of carbon steel tubes. Therefore, the experimental setup facilitates two plain sheets of the tube material. These sheets were moved towards each other while they were conductively heated by a high frequency elec- trical current. The heated sheets are pressed together to form a pressure weld. Therefore, the approach does not require a tubu- lar specimen or the whole process line to perform experimental investigations of the tube welding process. The approach allows the representation of the current distribution across the tube edges, the subsequent heating and temperature distribution as well as the mechanical and most geometrical conditions of a corresponding tube welding process. Experiments with a HFI- tube welding rig provided reference data from the tube welding process. The temperature distributions during the welding pro- cess, the microstructure in the weld cross section as well as the resulting hardness distribution were intercompared between the tube welding process and the experimental simulation to verify the simulation approach.
