Welding rivet joint for turbine, has supporting shaft, where turbine has bore, by which axial extension of shaft is partly projected

摘要

The welding rivet joint (1) has a supporting shaft (3), where turbine (2) has a bore (6), by which an axial extension (5) of the shaft is partly projected. A welding rivet (4) is welded by its front surface and deformed elastically with the front surface (7) of the axial extension. The supporting shaft is made from steel and the turbine is made from nickel-based steel alloy, preferably titanium and aluminum.
